In a heat engine, the temperature of the source and sink are 500 K and 375 K . If the engine consumes \( 25 \times 10^{5} \mathrm{~J} \) per cycle, find the heat rejected to the sink per cycle.

A \( 6.25 \times 10^{5} \mathrm{~J} \)

B \( 31.25 \times 10^{5} \mathrm{~J} \)

C \( 18.75 \times 10^{5} \mathrm{~J} \)
