Problem 2
One mole of monatomic ideal gas initially at absolute temperature and pressure is heated slowly at constant pressure to . It obeys , where is the gas constant; neglect macroscopic kinetic and potential energy changes. Take work done by the gas and heat entering it as positive. (a) Find the volume change and work done by the gas. (b) Find the change in internal energy. (c) Find the heat added and the ratio of heat to work.
