Consider 0.2 moles of a monatomic ideal gas that undergoes the cycle shown on the pV diagram below. The gas has Cy = 1.5R and Cp 2.5R. Assume that p-2po. V=2Vo, Po=1.01x105 Pa, and Vo=0.225m. For this problem we will be using the First Law of Thermodynamics used in class AEth = Q+ W, where energy transferred into the gas is positive and energy transferred out of the gas is negative. Please make sure you enter the proper plus or minus signs on the answers to each part of this problem.
