Explanation:
Given
Process
Work done for Polytropic process
where n=Polytropic index
![W=\dfrac{0.296(405-300)}{1.3-1}\quad [R_{N_2}=\frac{8.314}{28}]](https://tex.z-dn.net/?f=W%3D%5Cdfrac%7B0.296%28405-300%29%7D%7B1.3-1%7D%5Cquad%20%5BR_%7BN_2%7D%3D%5Cfrac%7B8.314%7D%7B28%7D%5D)
Now Calculating change in Internal energy
Now applying First law concept
