Answer to Question #58245 in Molecular Physics | Thermodynamics for frank godwin

Question

On a P-V diagram starting from an initial state P0 V0 plot an adiabatic expansion to 2V0 an isothermal expansion to 2V0 and an isobaric expansion to 2V0.

a) Use this graph to determine in which process the least work is done by the system
b) If, instead, the substance was compressed to V0/2, in which process would the least work done ?
c) Plot the processes of parts (a) and (b) on P-T diagram starting from P0 T0. Indicate expansions and compressions and be careful to show relative positions at the endpoints of each process.
