Essays on Air Bubbles

Pulmonary emphysema is a pathological condition of the lung tissue, which is characterized by its increased airiness due to the expansion of the alveoli, as well as the destruction of alveolar walls. This disease happens with males twice as often than with females. The risk of development of emphysema among people with chronic obstructive pulmonary illnesses is very high, especially after 55 years (Mayo Clinic Staff, 2014).

Factors that Provoke the Development of Emphysema

At the present time there are many causes and risk factors of pulmonary emphysema, with which a person meets almost every day. Some of them we will consider now. The main cause ...

Abstract

Solid waste and wastewater are primary sources of pollution from food processing industries. The wastewaters usually contain high suspended solids, organic starch and sugars that may contain toxic substances to the environment. Solid wastes come from organic materials while the mechanical preparation processes need biological treatment before releases into the environment. When untreated, they find their way into other water plants like lakes and streams. Since they have higher nutrient content, they result of eutrophication of the water systems hence causing algal growth. It, therefore, compromises the stability of the aquatic ecosystems as the water quality is changed. It ...

IntroductionYeast is a single-celled organism and is a type of fungi. Yeast has been used for centuries as the driving force behind the process of fermentation, which enables dough to rise into a loaf of bread. To make a loaf rise, yeast converts sugar (C6H12O6) and oxygen from the air (02) into carbon dioxide (CO2) and water (H20). When no oxygen is available, yeast will switch to an alternative pathway that does not need oxygen.Yeast metabolizes sugar (C6H12O6) to make carbon dioxide gas (CO2) and ethanol (C2H5OH) as end products. This carbon dioxide gas produced from yeast fermentation is responsible for the airy ...

Introduction

In this experiment, we are interested to determine the heat change of two different reactions using the ice calorimeter. The heat change values are applied together with the given values of the heat transformation of water (∆H(H2O)) and the application of hess law to establish the heat of formation of MgO (∆H(MgO)) A formation reaction has a defined stoichiometry which makes them ideal constructs to be investigated by the Bunsen ice calorimeter. When the heat is released by the reaction, it causes the ice to melt and the volume of the ice-water mixture to contract. From the ...
