An ideal gas with the adiabatic exponent undergoes a process in which its internal energy relates to

An ideal gas with the adiabatic exponent γ undergoes a process in which its internal energy relates to the volume as U = aVα, where a and a are constants. Find:
(a) The work performed by the gas and the amount of heat to be transferred to this gas to increase its internal energy by AU;
(b) The molar heat capacity of the gas in this process.
