Heat and Temperature

The transfer of energy from a high temperature body to a lower temperature body is known as heat. Heat travels in form of waves and like any other form of energy it has the potential to bring change into the matter it contacts. This process is usually accompanied by the transfer of entropy, the energy per unit temperature that goes unused. Heat transfer is usually generated by three types of thermal interaction, mainly, conduction, convection and radiation. Conduction is mostly related to the transfer of heat in solids, wherein the materials are in direct contact with each other and the heat ...

Abstract:

The principal intention of this study was to come up with the most conducive internal environment in a building. At any given moment, the internal temperature of a building is a function of the amount of heat produced by sources therein and the net heat transfer into or out of the building. The four heat transfer modes are convection, radiation, conduction, and phase- change. In executing this project, the researchers sought the relevant literature to establish the thermal properties of various materials. The properties are critical in determining the amount of heat inflow and exit from the building. The ...

Q.1
The condensation occurs due to change in temperature that causes the air to lose the ability to hold water vapor. Resultantly, the water liquefies, and appears as moisture around the bottle or cane filled with some sort of liquid. In July, the area of Tucson experiences difference in air temperature and the warmth dies out as air rises to higher altitudes with the passage of time, so the gaseous form of water takes the shape of liquid because the atmosphere lacks the power to hold the water vapor.
Q.2
The air that is present at ...

What is sunlight?

The sun provides tirelessly every square meter of the earth's surface, which it attacks, with an average of about 1370 watts of power (in the form of electromagnetic radiation). We say that the sun burns, but actually it does not. Instead, the sun is a giant nuclear reactor (Layton & Freudenrich, 2000). This solar energy is called the solar constant, since it does not change, except for minor fluctuations. Solar energy is sent in the form of light waves. Light is an electromagnetic wave. The frequency of light - or how fast the waves vibrate - determines the differences in color. ...

Introduction

In addition to their important roles in natural environ-
ments, microbial enzymes can be highly specific in their
activity and thus are increasingly useful in industrial
applications. Enzymes from aquatic bacteria adapted to
moderate and high temperatures have already figured in a
variety of applications, including polymerase chain reac-
tion (PCR), laundry detergents, protein recovery and
organic synthesis (e.g. Mullis and Faloona, 1987; Adams
and Kelly, 1995). Although enzymes with optimal activity
at cold temperatures have been understudied compared
with their heat-stable counterparts, increasing attention is
being paid to cold-active enzymes as potential applica-
tions are revealed
Enzymes are ...

1.0 Lab 1: Heating Value Measurements: Solid and Liquid Fuels with a Bomb Calorimeter
1.1 Introduction
Measurements of heating values can be derived for both solid and liquid combustible fuels using an Oxygen Bomb Calorimeter. The calorimeter measures heat. Heat is not the same thing as temperature. The heat of combustion is called the calorific value. The calorific value is “:the number of heat units liberated by a unit mass of a sample when burned with oxygen in an enclosure of constant volume” (Introduction 2007). The experiment uses the 6100 Bomb Calorimeter. The definition of calorific value in a bomb calorimeter ...

Introduction

Air Conditioning is perhaps one of the most wonderful scientific inventions that provided relief to the people living in a hot climate. What started as a device for cooling homes was later extended to vehicles that have a closed structure. For a layman, it appears that an air conditioner cools the air. However, scientifically speaking, the air conditioner provides cooling by transferring heat from the air inside the thermally insulated place to the air present outdoor by the medium of “refrigerant”. The phenomenon of heat transfer involves three physical processes: evaporation, compression, and condensation (“How Does an Air Conditioner Work?”). Firstly, ...

Introduction

Fire is described as the visible result of an oxidation process in the chemical reaction known as combustion. Combustion occurs between an oxidant (source of fuel) and oxygen which results in the release of heat and the source of fuel being converted into another form (Grimwood et al., 2010). When heat is released, light is produced either as a flame or glowing. The fuels which bring about combustion are mainly organic compounds like hydrocarbons which may be in the solid, liquid, or gaseous phase.
The part of the fire which is visible is known as the flame. It is ...

Technique for Detecting Kepler 186

The method used to detect Kepler 186 is transit technique. A planet is described as transiting when it passes between its star and the planet Earth. As the planets of Kepler 186 pass between the Earth and the Kepler 186 star, the star's light is caused to dim, and this is detected by an instrument. ...

The human body consists of trillions of cells that work together synchronously for the maintenance of an organism. The metabolic needs of all the cells in the body are almost similar. For the well-being of a human body and the proper functioning of all the cells, constant internal environment needs to be maintained by providing the cells with oxygen and nutrients (Homeostasis and Regulation in the Human Body < OpenCurriculum, 2016)
The internal environment of the body is tissue fluid, which bathes all cells making up the body (Mader, 2016). The composition of the tissue fluid must always remain ...

Terrestrial Ecosystems Dynamic

Ecological systems are dynamic by nature and constantly feel the influence of climate variability. Since the structure and functioning of forest ecosystems are controlled by climatic factors through metabolic function, it may change in the future dynamics of forest restoration, growth, progress and growth of tree mortality, as well as the relationship of rocks. It is expected that climate change will be faster than the rate at which ecosystems can adapt and repair itself.
Ecosystems of the North must first of all respond to possible global warming because of climate-driven ecosystem response reveals itself most clearly. At high ...

The surface of the Sun has a temperature of about 5800 K. The core of the Sun has a temperature ranging from 10 – 15 million Kelvin. This temperature range is high enough to activate nuclear fusion within the Sun. Here, four protons will fuse together to obtain a helium nucleus containing two protons and two neutrons via a proton-proton chain. The core of the ...

Meissner effect is one of the remarkable properties of superconductors. Most superconductors are metals and metal alloys. However, some non-metals also exhibit superconductive properties hence they are regarded as superconductors. A superconductor refers to a material that can transfer electric current with zero resistance. This implies that when electric current is passed through a superconductor at a temperature below the critical temperature value (Tc), no energy is lost in any form: sound, heat, or light. It is important to point out that superconductivity of a material can only be observed at temperature below the critical temperature (Tc). Critical temperature values vary from one ...

General overview

Preparation of yoghurt takes place through milk fermentation process with various cultures of bacteria comprising of streptococcus subspecies mixed with lactobacillus delbrueckii subspecies and thermophiles (Barbano, 2009). Basically, yoghurt comes in two types: distilled and set (Augustin et al., 2003). The author further explains there is a difference in the main procedure through which these yogurts are manufactured. In the set yoghurt (inclusive of fruit on the bottom), the formation takes place in retail pots as the fermentation of the lactic acid bacteria proceeds into lactic acid generating a structure of continuous gel in the container of the consumer. ...

Global warming is one of the biggest challenges the world is facing now. Also known as climate change, global warming is the gradual change in the average temperature of the planet’s atmosphere. This change in temperature is believed to be permanently changing not only the atmosphere’ temperature but also that of the world’s oceans. The increase in the carbon dioxide level and the depletion of the ozone layer is one of the primary reasons that have been accused of the increased climate change. The ozone layer is responsible for the protection of the earth from the dangerous ...

Introduction

Enzymes are proteins which have the ability to facilitate metabolic reactions without being used up in the reaction. The enzyme amylase is responsible for facilitating the hydrolysis of starch to form sugars that are then assimilated by the body. Amylase is an enzyme needed for the digestion of carbohydrates for nutritional purposes. Starch is one of the most important sources of energy in the body. Starch is a polymer made up of several monosaccharide and disaccharide monomers. However, starch cannot be absorbed and used in the body as it is (Cornish-Bowden, 134). Consequently, it has to be digested into smaller ...

Introduction

The activities that take place in a living organism are mainly controlled through the use of enzymes. Enzyme refers to a molecule that is protein in nature and functions as a catalyst to speed up the rate of a given reaction. An enzyme as a protein molecule has three main characteristics. First, an enzyme has its basic function is as to increase the reaction rate and this makes most of the cellular reactions occur more than million times that they would have if the enzyme was absent. Second, almost all enzymes act in a specific manner with only one substrate in order to produce the ...

Climate Changes and Ozone Depletion

The weather is changing but where and when is very unpredictable. Sometimes it is changing in slow ways but sometimes weather events are very extreme and dangerous. The Intergovernmental Panel on Climate Change (IPCC) in 2001 reported on the “probability of the world being three degrees Celsius hotter by the end of the century and of a distinct possibility of it being almost six degrees hotter” (Lovelock, 2008, p. vii). This is a very scary prediction Ozone depletion is a different type of problem although Henson (2008) has said that the ozone depletion problem does have some ...

Global warming refers to a system of climate changes that are responsible for causing an increase in the average temperature of the lower atmosphere which affects the average thermal gradient of the Earth. Global warming may have a great variation among the causes, but it is most principally associated with human interference, specifically with the release of excessive amounts of greenhouse gases”. The most popular and common definition of the global warming is “Warming caused by human activity.” (Weather Street)
There are several gases in the Earth’s atmosphere which are responsible for the increase in the global temperature ...

Question 1: Pathophysiology of Mr. Jensen’s post-operative hypovolemia

Hypovolemia is a surgical condition that indicates the rapid fluid loss that may result in organ failures. The outcomes of the hypovolemia are mostly due to insufficient circulating volume or scarce perfusion. Often hypovolemia is secondary to hemorrhage the reason of which includes severe internal or external blood loss and GI, thoracic and abdominal bleeding maladies (Devitt, 2001).
Hypovolemia involves significant fluid loss other than blood that can be further accompanied by refractory gastroenteritis and widespread burns. Hypovolemia may develop in post-surgical incidence, bone fracture, due to ...

Introduction:

The debate surrounding global warming is important due to the growing concern of potential consequences for not only humans, but all that inhabit the Earth. A changing climate produces uncertainty regarding the future, which places a great deal of stress on human institutions as well as the natural ecosystem. However, others argue that the effects on the environment are primarily natural processes and were not impacted by human behavior. In assessing the current state of research regarding this debate a better understanding of the contribution that various activities have on the climate can be attained. This can help to ...

Climate Change

Earth is the only planet in the universe that supports life, and this uniqueness is attributable to its optimal temperature and climatic conditions. Earth’s temperature is affected by variations in solar energy that reach earth, changes is earth surface as well as atmospheric reflectivity, as well as changes in concentration of greenhouse gases (EPA, 2016). Earth’s distance, rotation in its axis and revolution around sun in its orbit primarily determine change of seasons in earth, as well as its climatic patterns. Variations in light reflectivity or albedo of various surface features on earth also contribute to climate ...

Difference between freshwater lakes and oceans in terms of the formation of ice

Ocean ice is found in Polar Regions. It covers an area of 25 million square kilometers. Ocean ice forms on the surface of the ocean. It grows and melts above oceans. During winter, ocean ice grows but melts during summer (Thompson & William 1). The occurrence of ocean ice has a direct influence on the global climate. Ocean ice has a bright surface that reflects most of the light that strikes it. The co sequence of this phenomenon is that areas that the ocean ice covers have low absorption of solar energy (Ilker 149). In this regard, the temperatures in the solar ...

Global warming has evolved into a demure problem in the present-day world. The problem is very serious, as it concerns a possible lift of temperature and climate alter. Climate warming is a slow and gradual upsurge in the medium temperature on our planet that there is currently. Climate warming is a fact, with which to argue is pointless, and it is therefore necessary to take a sober and objective approach to its understanding. The Earth is warming and this has a tragic effect on the glaciers of our planet. The temperature surges, the ice begins to melt, and the sea level begins to rise. This ...

There are many limiting factors in a marine ecosystem. These limiting factors interact in many ways to form different features and also affect the marine ecosystem. This paper analyzes the relationship between the temperature of the region and rate of evapotranspiration, the upwelling of water and the speed of wind, the ocean currents and the climate experienced, and nature of rocks and type of features formed.
The temperature of the surrounding region in an ocean is very important. When temperature is high, the evaporation from the surface of the ocean would be high (NSIDC, n.d). In addition, high temperature ...

Enzymes are large protein molecules which are vital in carrying out the chemical reactions responsible in maintaining homeostasis in our body systems. There are various factors which affects the functions of our enzymes. These factors include: enzyme concentration, substrate concentration, inhibitors, temperature, and pH (Voet and Voet, 2011). Given an adequate concentration of substrate, an increase in enzyme concentration will increase enzymatic reaction rates (Uddin, 2012). The relationship of substrate concentration to the function of enzyme is best explained by the Michaelis-Menten equation:
V1 = (Vmax [S])/( Km + [S])
where:
V1 = velocity at any time

It is well documented that human beings are capable of thriving and surviving in the harshest of conditions ranging from the arctic to the equator and with different forms of lifestyles and diets. One of the reasons’ for this is not farfetched, it is the ability of the human body to adapt to various conditions and in turn maintain homeostasis. Homeostasis refers to the human body's ability to regulate her internal environment physiologically in a bid to ensure and maintain stability in response to the instability and fluctuations of the weather and the external environment. Also, homeostasis refers to the ...

1.0 introduction
Thermoregulation is basically temperature regulation. It is a homeostatic process where by the internal temperature of an organism is kept constant within a specific range despite fluctuations in the external temperatures. It is important to note that all homeostatic systems use negative feedback mechanism. This implies that whenever there is a change in external or surrounding temperature of an organism, consequently a corrective mechanism is initiated within or without the organism to counter the change. Not all animals can maintain a constant body temperature; this is possible only for birds and mammals. Such animals are referred to as endotherms or commonly ...

Summary Report 1

What factors contributed to the problem?
Volcanic activity is a major contributing factor to the issue of climate change. The eruption of volcanoes leads to the release of large quantities of water vapor, ash, dust, carbon dioxide, and sulfur dioxide into the atmosphere. In the atmosphere, these sulfur dioxide molecules will react with water vapor leading to the formation of sulfuric acid, which is then spread all over the world through winds. The sulfuric acid formed in the atmosphere can significantly affect the amount of solar radiation entering the Earth’s surface and thereby the ...

For example, it can be a change in weather conditions, or distribution of them per average conditions. It`s usually caused by different factors of biotic origin like ...

Question 1-Oceans and Climate Change:

Global warming has a multiplier effect and one of the elements that will significantly experience climate change is the ocean. The temperature of the ocean carries much sensitivity to the ocean life that inhabits it. Land temperature is quicker to show changes due to climate change and the ocean takes longer to reflect those changes. However, even the slightest change in temperature can have an effect to certain species. Sea temperature rise is a serious concern to environment scientists and ocean life is faced with threat.
There are natural climate changes and man-made climate changes also known as anthropogenic . Most ...

The study of meteorological materials in all regions of the globe, prove that the climate is not constant, but is a subject to some certain changes. Beginning in the late XIX century, warming particularly intensified in 1920-30., but then a slow cooling started, which ended in 1960. Geologists’ studies of the earth's crust of sediments have shown that in the past era there was much greater climate change. These changes happened due to natural processes, that is why they are called natural (Martelle, 2013).

The following effects of global warming are projected:

Introduction

Food items are always prone to spoilage which in most of the cases is precipitated by an increase in bad microbes that cause the food to change its property and thus food becomes unsafe for eating. The main purpose of inspection of food is to trace the presence of bad microbes that are available in most of the food products but below certain level they are harmless. Microbes are nothing but cells which are so microscopic that it is not possible to detect them when they are in very small numbers. In order to detect the presence of harmful ...

There is one very famous quote which says, “Water is life’s mater and matrix,

mother and medium. There is no life without water”. The adage highlights the importance

of water and its value in sustenance of living beings on earth. It has multiple uses and each

use supports life, directly or indirectly. Even though 75 percent of our Earth is covered with

water, less than two percent is fresh water. To make the matters worse, only about a

percent is available as drinking water (two percent is frozen) (SSCWD, 2012). The facts

above, at the very outset, bring about the priceless importance of water.

Though once it was considered to be an endless natural ...
