Problem
Two moles of an ideal monatomic gas, initially at pressure p1 and volume V1, undergo an adiabatic compression until its volume is V2. Then the gas is given heat Q at constant volume V2.
(a) Sketch the complete process on a p−V diagram.
(b) Find the total work done by the gas, the total change in its internal energy and the final temperature of the gas. [Give your answer in terms of p1,V1,V2,Q and R ]
