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 po of the gas. Give your answer in terms of T and Vo. (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?
