n moles of a monoatomic gas is carried round the reversible rectangula

1.	n moles of a monoatomic gas is carried round the reversible rectangular cycle ABCDA as shown in the diagram. The temperature at A is T_0. The thermodynamics efficiency of the cycle____
Answer» `15%` `50%` `20%` `25%` SOLUTION :For N MOLES of monoatomic gas At A temperature =`T_0`, Volume =`V_0` , Pressure = `P_0` At A, `P_0V_0 =nRT_0` (cold) At B, `2P_0V_0=nRT` (HIGH) =T.=`2T_0` Maximum thermal efficiency of the reversible engine of this carnot.s cycle . `=eta=1-T_0/T=1-T_0/(2T_0)=1/2`=50%
