1.	Figure below shows two paths that may be taken by a gas to go from a state A to a state C. In process AB, 400 J of heat is added to the system and in process BC 100 J of heat is added to the system. The heat absorbed by the system in the process AC will be .....
Answer» 380 J 500 J 460 J 300 J Solution :In CYCLIC process ABCA, `DeltaU_"cyclic"=0` `Q_"cyclic"=W_"cyclic"` `Q_(AB)+Q_(BC)+Q_(CA)` = closed loop area `400+100+Q_(CA)=1/2` BASE x HEIGHT `500-Q_(AC)=1/2xx2xx10^(-3)xx4xx10^4` `500-Q_(AC)=40` `therefore Q_(AC)`=460 J
