1.	A cyclic process involves three processes: A to B, B to C, C to A, heat exchanges during processes are: `Q_(AB)=+40J` `Q_(BC)=+20J` `Q_(CA)=-10J` Find net work done and efficiency.
Answer» `sumQ=40+20-10=50J`. `sumQ_(+ve)=40+20=60J` For cyclic process `sumW=sumQ=50J` [As `DeltaU=0`] `implies eta=(sumQ)/(sumQ_(+ve))=(50)/(60)=(5)/(6)`
