Questions
An ideal gas expands isothermally from a volume V1 to V2 and then compressed to original volume V1 adiabatically. Initial pressure is P1 and final pressure is P3. 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 done W=W1+−WA∵ WA>W1⇒W<0Talk to our academic expert!
