In a two-step process, heat is allowed to flow out of an ideal gas at a constant volume so that its pressure drops from 2.2 atm to 1.4 atm. Then the gas expands at constant pressure from a volume of 5.9L to 9.3L. In going from point (a) to point (c) : a) Is the gas hotter, colder, or the same temperature at point (c) as at the beginning (a)? (Hint: consider the ideal gas law.) b)what is the total work done by the gas in the process? c) what is the total heat flow and is it into or out of the gas?
