2. n=0.0301 moles of a monatomic gas is trapped in a cylinder with a piston that can move in and out. The gas undergoes the cycle A ->B->C->A as shown on the P-V diagram below. One step of the cycle is isothermal, another is isovolumetric, and the other is isobaric.

During which part of the process does the gas do the most work on the piston? Circle one: A + B B -C C-7A Explain/Justify your answer: d. What is the temperature (in K) of the gas at step C of the cycle? Justify your
