An ideal gas initially at a state (P1,V1) is allowed to expand isothermally to a state (P2, V2). Then the gas is compressed adiabatically to its initial volume V1. Let the final pressure be P3 and work done by the gas in thewhole process be W, then(A) P3>P1 and W<0(B)P3>P1 and W>0(C) P3<P1 and W>0(D) P3<P1 and W<0Dont just tell me the answer but also tell me how to get the answer.
