Questions
An ideal gas expands isothermally from a volume and then compressed to original volume adiabatically. Initial pressure is and final pressure is . The total work done is W. Then
detailed solution
Correct option is C
From graph it is clear that P3 > P1. Since area under adiabatic process (BCED) is greater than that of isothermal process (ABDE). Therefore net work doneW = Wi+(-Wa) ∴ Wa > Wi ⇒ W < 0Talk to our academic expert!
