10. In this course you investigated a number of issues related to the effects of chemicals on humans and the environment. Choose one chemistry issue related to the impact of human activity on air quality to focus on as you answer the following questions, for example CO₂, CFC's, SO₂, or other) a. What human activity (or activities) causes the problem? b. What specific chemical(s) are problematic? Be specific in describing the nature of the problem, including any relevant chemical reactions. c. How are humans using their understanding of chemistry to help understand and/or solve the problem? Criteria: identify the human activities responsible for adding unwanted compounds into the atmo- sphere with relevance. explain the specific threat that CFCs presented to the atmosphere, and describe how deci- sive action by governments helped to mitigate this threat with clarity and logic. identify a variety of chemical reactions that have an effect on the environment with logic and relevance. apply my understanding of chemical reactions to real-life contexts with relevance and flu- ency. evaluate the benefits and risks of our use of fossil fuels with logic and significance.
Ideal and Real Gases
Ideal gases obey conditions of the general gas laws under all states of pressure and temperature. Ideal gases are also named perfect gases. The attributes of ideal gases are as follows,
Gas Laws
Gas laws describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. The very first observations about the physical properties of gases was made by Robert Boyle in 1662. Later discoveries were made by Charles, Gay-Lussac, Avogadro, and others. Eventually, these observations were combined to produce the ideal gas law.
Gaseous State
It is well known that matter exists in different forms in our surroundings. There are five known states of matter, such as solids, gases, liquids, plasma and Bose-Einstein condensate. The last two are known newly in the recent days. Thus, the detailed forms of matter studied are solids, gases and liquids. The best example of a substance that is present in different states is water. It is solid ice, gaseous vapor or steam and liquid water depending on the temperature and pressure conditions. This is due to the difference in the intermolecular forces and distances. The occurrence of three different phases is due to the difference in the two major forces, the force which tends to tightly hold molecules i.e., forces of attraction and the disruptive forces obtained from the thermal energy of molecules.
