A cylinder contains 4 mol of an ideal gas at 30^oC. If it expands from an initial volume of 1.0 m³ to 2.0 m³ while maintained at a constant pressure of 200 kPa.

What is the change in the temperature of the gas?
How much heat is absorbed or released from the system, over the process?

The pressure is then reduced while the gas is held at a constant volume.

If over this process the gas is returned to its original temperature, what is the heat absorbed or released, over that process?
