Two moles of an ideal monatomic gas, initially at pressure `p_1` and volume `V_1`, undergo an adiabatic compression until its volume is `V_2`. Then the gas is given heat Q at constant volume `V_2`.
(i) 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 `p_1,V_1,V_2, Q and R`]
