Answer to Question #95480 in Electrical Engineering for Anthony

Question

0.05m^3 of a gas at 6.9 bar expand reversibly in a cylinder behind a piston according to the law of pv^1.2=constant until the volume is 0.08m^3. Calculate the workdone by the gas and sketch the process on p-v diagram.

Answer 1

1. Calculate the pressure when the gas expanded to 0.08 cubic meters:

2. The work in the process is

3. The process on p-V diagram looks like
