A cylinder contains 2 moles of an ideal monatomic gas that is initially at state A with a volume of 0.01 m^3 and a pressure of 4.0x10^5 Pa. The gas is brought isobarically to state B, where the volume is 0.02 m^3. the gas is then brought at a constant volume to state C, where its temperature is the same as at state A. the gas is then brought isothermally back to state A.
A) Determine the pressure of the gas at state C.
B) State whether the work done by the gas during the complete cycle is positive, negative, or zero, and explain why.
C) Is this device a refrigerator or a heat engine? Why?
