An ideal gas expands isothermally from a volume 
to 
and then compressed to original volume 
adiabatically. Initial pressure is 
and final pressure is 
. The total work done is W. Then
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
From graph it is clear that 
.
Since area under adiabatic process (BCED) is greater than that of isothermal process (ABDE). Therefore net work done
