Extracted text: One mole of an ideal monoatomic gas at temperature T is contained in cylinder with initial volume Vo, diathermal walls, and a moveable piston. The gas is expanded isothermally and quasi-statically to a final volume of 2V,. Answer the following ques- tions: (a) Find the initial pressure p, of the gas. Give your answer in terms of T and V. (b) Find the final pressure of the gas. Give your answer in terms of po. (c) What is the change in internal energy of the gas, AU?
