Questions for Unit 12
Q 1 : One mole of an Ideal Gas in a container is at a pressure of 2.5 atm and a volume of 9.0 x 10^-3 m^3. The gas undergoes three processes. First, it expands at constant pressure to 12 x 10^-3 m^3. Second, it cools at constant volume to its original temperature. Third, it contracts to its original volume at constant temperature. What is the change in internal energy and the heat flow into or out of the gas as it undergoes each process?
