A Carnot engine working between 300 K and 600 K has work output of 800 J cycle-1. The amount of heat energy supplied from the source of engine in each cycle is

The efficiency of Carnot engine is given byη=1−T2T1Given,   T1=600K,T2=300K∴ η=1−300600⇒ η=1−12⇒η=12=50%Also,   η=WQ⇒800Q=12Thus, amount of heat supplied from source to engine isQ=800×2=1600J
