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

Professor PC Thomas Classes · Answer

The efficiency of heat engine is defined as $\frac{\mathrm{W}}{\mathrm{Q}_{1}}=1-\frac{\mathrm{T}_{2}}{\mathrm{~T}_{1}}$ Where W is the work output. $\mathrm{Q}_{1}$ is the amount of heat supplied to the engine from the source.\ $\mathrm{T}_{1}$ is the temperature of sink\ $\mathrm{T}_{2}$ is the temperature of sink.\ $\frac{800}{Q_{1}}=1-\frac{300}{600} \Rightarrow Q_{1}=1600 \mathrm{~J}$\
