E$.$ a$.$ A gas at $100C$ is expanded isothermally and reversibly from $10$ Bar pressure to $1$ bar. Calculate:

i$.$ The specific work transfer.

ii$.$ The specific change in internal energy.

iii. The specific heat transfer

Take $C_v=718\frac{j}{k}gK$ and $R=287\frac{J}{k}gK$

b$.$ Repeat this for an Adiabatic process with index $=1\mathrm{.}4.$

c$.$ Repeat this for a polytropic process with index $n=1\mathrm{.}2.$
