Essays on Boiling

The British Isles, a group of islands in the Atlantic Ocean, is packed with mouth-watering and sumptuous food varieties. Countries that comprise the British Isles have followed entirely different paths. While Britain's cuisine has been shaped by its history of colonization, the cuisines of Scotland, Ireland, and Wales have predominantly developed as a weak/peasant cuisine that emphasized on survival than celebration. Despite different paths followed by these various countries, many aspects tie the modern day cuisine, and there are several classic dishes that are common to all nations. The Celtic connection has made many ties and links between the ...

A lot of food is wasted in American food stores and according to the movie Dive!, more of this food should be given out to needy people who need it. Water is also considered part of food and on equal measure, just like food, it should not be wasted. Instead, there should be a moderate use of it to avoid wastage. Hone water filters or rain filters offer an efficient way of reducing water. Just like any other food, water needs to be used sparingly because some areas in the US are forced to go through rationing due to ...

Multiple factors went into play before the Europeans claimed dominance over world trade routes and conquered vast lands outside Europe. With a particular interest in the fact that the Chinese boasted better navigation tools and sea vessels than the Portuguese and the Spanish did by the fifteenth century (World Shrinks17mins), the rise of the West benefited greatly from the lack of competition. In other words, if the Chinese had maintained their desire to show their military prowess to other nations, then the West would have taken longer if not failed to come into power. A view of the animated ...

California’s “third city” San Diego is oftentimes forgotten between San Francisco’s foggy weather, Golden Gate Bridge and tech industry connections; and Los Angeles’ sports teams, movie stars, and of course, Hollywood. To be sure, what San Diego is popularly known for, namely its beaches, its great weather, and its zoo, are hardly the attractions that provoke excitement and “must go” desire. Rather, the city’s attractions they seem to focus on rest and relaxation. Indeed, that is probably why San Diego is one of the top cities in the nation for conferences and conventions. Indeed, one of ...

Introduction

Water is termed the ‘universal solvent’ since it is capable of dissolving a large variety of substances. These solutes can be broadly classified as ionic and molecular solutes, based on their behaviour in solution. Ionic solutes dissociate into their constituent ions when dissolved in water. An example of this class is sodium chloride (common salt). Molecular solutes are dissolved as uncharged molecules, like sucrose (sugar). The effect of ionic solutes on the boiling point of water is the focus of this project. Boiling occurs when the vapour pressure above a liquid equals the pressure over it. Hence, the normal ...

Explain Hardness of Water

Explain Hardness of Water The water that occurs in nature always contains salts, which exist in water as positive and negative ions. The salinity of fresh water is 1000 mg/L (1L of water contains 1000 mg of various salts or ions). The typical cations present in natural water are sodium, potassium, calcium and magnesium; the most common anions are chloride, sulfate, bicarbonate, nitrates, etc. Hardness of water refers to presence of calcium and magnesium ions. When water is heated, the reaction (Tebbutt, 1999):

takes place. Calcium carbonate, unlikely other salts, is insoluble and forms precipitate. The precipitate is ...

Never a spontaneous phenomenon, racism seems sparked often as an ideological view. Unlikely though it may sound, the white liberal government instituted what continued for over 40 years. Characterized by segregation and violence in response to any opposition, the order came to its end. While in the transitional period, the country established the Truth and Reconciliation Commission for the restoration of national unity. Obviously, national reconciliation is possible only through racism eradication since it is racial bias that is at the root of the national disunity and bellicosity. Much as the commission utilized a number of tools towards this ...

Question 1: reasons why references are used for technical or academic writing

In technical and academic writing, referencing may be applied to ensure that previous information on a certain subject is acknowledged. The writer, in this case, is able to indicate that indeed he or she has researched related literature concerning the topic at hand and provides information on what has been achieved in the topic of concern. Consequently, once the previous literature has been acknowledged, the writer is able to table his or her position based on the previous information thereby providing a basis for the argument or claim they intend to make. Thirdly, referencing is done to ensure that ...

The periodic table of elements, by far, stands among the most notable discoveries in the history of chemistry. Nowadays, probably everyone who has ever heard about chemistry heard about the periodic table of elements. Its implications on the scientific world are so enormous that it has even leaked out to the general public and have become associated with the chemistry itself. This is not surprising considering the scientific strength of this instrument. Using the periodic table, many characteristic properties of the elements can be predicted and many phenomena can be explained. This discovery put so much scientific knowledge together, ...

Maintenance of ethical principles is essential to the sustainability of the globe. In fact, lack thereof compromises the development of humanity, and this situation could result in unpleasant behavior. With this in mind, it is worth acknowledging the fact that the current controversies associated with the inhumane treatment of animals are justifiable. Specifically, the process of preparing animals for consumption is primarily based on the final presentation to the consumer and not the welfare of the animals. As such, this situation questions the ethical principles of the individuals who consume meat. According to McClelland (4), inhume treatment of animals ...

The best recipe for a dish to be delicious is preparing it with love – Tita, the heroine of “Like Water for Chocolate” by Laura Esquivel, is sure. That is certainly the formula Esquivel resorts to creating her novel, where love is a key ingredient, and the food for thought produced by the book is savory, hot and rich. “Tita remembered that Nacha had always said that when people argue while preparing tamales, the tamales won’t get cooked. They can be heated day after day and still stay raw, because the tamales are angry. In a case like that, ...

Introduction

A pressure cooker is a hermetically sealed pot that utilizes the thermodynamic principles of steam pressure to cook foods faster than conventional cookers, and use energy more efficiently. Though pressure cookers have existed for many years, they have lately gained considerable popularity as they are considered to be among the beast means for healthy cooking in the market. Moreover, pressure cookers are very simple to use, and the resulting appearance and flavor of foods cooked in them make it difficult to believe how fast the cooking process is actually completed. This paper will focus on the thermodynamic principles under ...

How did Annie’s fiber intake compare to her target of 25 grams? Give 4 examples of foods that Annie could include to increase her daily fiber intake (identify foods that ...

Morality is essential to the stability of a nation or an organization. In fact, lack thereof leads to the development of uncertainty among individuals and this situation compromises peace. With this in mind, it is worth acknowledging the fact that David Foster raises his ethical concerns about the consumption of lobsters. Precisely, he does not present his argument in a way that castigates this action. Rather, he poses a question that challenges one’s emotional and logical appeal. He mentions, “Is it all right to boil a sentient creature alive just for our gustatory pleasure?” This statement forms the ...

Abstract

Color and texture are important attributes related to vegetable quality. The objective of this study was to determine the changes in quality characteristics, caused by cooking time, and pH (alkali and acid addition) in some vegetables. Four different vegetables — carrots, spinach, red cabbage and cauliflower — were analyzed for changes in color and texture associated to time of boiling, the effect of alkali (baking soda), and the effect of acid (vinegar and cream of tartar). Samples of each vegetable were prepared and treated for five minutes. Color change was measured visually and using the L*a*b* technique. Color and ...

I. Introduction Advances in recombinant DNA technology and bioinformatics-based data analysis have driven the explosion of structural biology in the last two decades (Kelly, Jess, and Price 119). This has resulted to the identification of at least 2000 proteins annually and a growing need in performing structural studies in these new proteins. The current trend involves the concern of analyzing protein structures close to its natural conditions (and other conditions) and of measuring their rates of structural changes, an essential factor in their biological functions. The technique of circular dichroism (CD) has gained an increasing popularity in addressing these ...

BIO 103

Introduction: Plant cells photosynthesize to produce glucose. By doing this, light energy, coming from the sun, is transformed in chemical energy, glucose. Oxygen is also produced from carbon dioxide and water. The process occurs by light dependent reactions (in thylakoids) and dark dependent reactions (in the stroma). In the light, plants produce energy molecules, such as ATP and NADPH; in the dark, they use those molecules to fix the CO2. The excess of glucose during photosynthesis can convert into starch.

Purpose:

The purpose of this experiment was to determine the differences between leaves from plants exposed to the sun and ...

The Oxford Dictionary defines science as the intellectual and practical activity encompassing the systematic study of the structure and behavior of the physical and natural world through observation and experiment. In order to develop the LifeStraw, scientific experiments were conducted to understand the process of water purification and develop an innovative method ...

Introduction

The fundamental process of thermal power plants is based on the conversion of thermal energy into mechanical energy and, subsequently, into electric power, using steam as the working fluid. According to the U.S. Energy Information System, over 67% of the electrical energy in the United States is generated through thermoelectric power plants, which use the combustion of fossil fuels such as natural gas, coal and petroleum to generate the steam necessary for the process; moreover, thermoelectric power generation accounts for an approximate 80% of all the power generation worldwide. Thus, the electricity consumed in most homes and industries is ...

Background information

The need for clean water for use by humanity has since time immemorial been an area of concern with scientists and scholars inventing methods that prove to be more efficient than their predecessors. The ultimate goal has always been the removal of undesirable chemicals and pathogens that would, however, render the water unfit for human and industrial consumption. In today’s contemporary society, human activity has culminated into pollution of the natural environment including water catchment areas. This has therefore made water unfit for consumption thereby prompting for more cost-effective and efficient methods for purification of this natural resource. ...

Humankind records show that one of the oldest beverage in existence to date is beer. Beer can be described as an intoxicating beverage produced by a process called fermentation. There is also an array of types of beers, this dictated by the different methods of preparation, raw materials and flavours included in brewing. The types of beer’s are as follows; ales, lagers, stouts and porters as well as malts. The consumption of a beer in a local bar begins from the brewery which acquire necessary resources, convert them to the taste akin the type and flavor of beer ...
