Question 1. What are the four properties that describe a gas and how does these properties affect one another. For examples when one property increases the other one does what?
Question 2. Give some laboratory situations or chemistry problems where you could use this information.
Question 3. Why is the identity of a gas not included in the combined and ideal gas law? For example, carbon dioxide has a larger molar mass than hydrogen, yet the molar mass is not included in either the combined gas law or the ideal gas law.
Question 4. Give some specific laboratory or chemistry problem where the identity of the gas is needed or one where it is not needed.
