How to solve

One mole of an ideal gas with $C_p=(\frac{5}{2})R$ and $C_v=(\frac{3}{2})R$ expands from $P1=6$ bar and $T_2=800K$ to $P_2=1$ bar by each of the following paths:

$($a$)$ Constant volume

$($b$)$ Constant temperature

$($c$)$ Adiabatically

Assuming mechanical rqversibility, calculate W$,$ Q$,U$ and $H$ for each process. Sketch each path on a single PV diagram.
