Answer» Solution :(a)`""(PV)/(R)= (20 XX1)/(0.0821) = 243.6 K` `T_(2) = (20 xx 10 )/(0.021) = 2436.0 K` (b)CA(Isothermal ) `W_(1) = - 2.303 xx 2 xx 243.6 log .(2)/(20)= 1122` BC(Isochoric ) `W_(2) = 0` AB(Isochoric) `W_(3) = - RDeltaT = - 4384.9 cal` For complete CYCLE `W = W_(1) + W_(2) + W_(3) = 3262. 888 cal`
