Question on Thermodynamics-First Law

Consider a compressor with air at 1 bar and 15 degrees Celcius, compressing (a) isothermally to 27.59 bar, and (b) polytropically, the index being 1.3 to the same pressure. Compare the work done, the heat exchange with the surroundings, the final temperature, and the changes in internal energy and entropy due to the compression per unit of mass of air.

sir, I can’t able to find initial and final volume of the processes in order to find the Work done of the two processes. kindly help me with this.

Can you share what you could do?

Hey @ashokraja94 try harder mate! share what you could do? We will be happy to help!
