Question
A thermodynamic process of one mole ideal mono atomic gas is shown in figure. The efficiency of cyclic process ABCA will be :
Options
A.25%
B.12.5%
C.50%
D.100/13%
Solution
W = 
P0V0 , TA =T0 , TB = 2T0 , TC = 4 T0
Heat supplied = QAB + QBC = CVT0 + CP2T0 =
RT0 = P0V0
∴ Efficiency =
× 100
=
× 100 = 7.7 %
