Vedclass · Answer

(A) Given: Heat supplied by the source $Q_1 = 200 \, cal$,Heat rejected to the sink $Q_2 = 150 \, cal$,Temperature of the source $T_1 = 400 \, K$.For a reversible heat engine,the ratio of heat exchanged is equal to the ratio of temperatures: $\frac{Q_1}{Q_2} = \frac{T_1}{T_2}$.Rearranging the formula to solve for the sink temperature $T_2$: $T_2 = \frac{Q_2}{Q_1} 	imes T_1$.Substituting the given values: $T_2 = \frac{150}{200} 	imes 400$.$T_2 = 0.75 	imes 400 = 300 \, K$.Therefore,the temperature of the sink is $300 \, K$.

$A$ heat engine receives $200 \, cal$ of heat and rejects $150 \, cal$ of heat. If the temperature of the source is $400 \, K$,what is the temperature of the sink in $K$ (in $, K$)?
