1.	A thermodynamic process of one mole ideal monoatomic gas is shown in figure. The efficiency of cyclic process ABCA will be
Answer» <P>0.25 0.125 0.5 0.077 Solution :`W=(1)/(2)P_(0)V_(0), T_(A)=T_(0),T_(B)=2T_(0),T_(C)=4T_(0)` Heat supplied =`Q_(AB)+Q_(BC)=C_(V)T_(0)+C_(p)2T_(0)` `=(13)/(2)RT_(0)=(13)/(2)P_(0)V_(0)` `therefore` Efficiency of the cyclic process `((1)/(2) P_(0)V_(0))/((13)/(2)P_(0)V_(0))xx100=(1)/(13)xx100=7.7%`
