A Carnot engine operates between two reservoirs of temperatures \(900\; \mathrm{K}\) and \(300 \;\mathrm{K}\) The engine performs \(1200\; \mathrm{J}\) of work per cycle. The heat energy (in \(\mathrm{J}\) ) delivered by the engine to the low temperature reservoir, in a cycle. is
- A \(450\)
- B \(500\)
- C \(600\)
- D \(650\)
Answer & Solution
Correct Answer
(C) \(600\)
Step-by-step Solution
Detailed explanation
for carnot engine \(\frac{Q_{1}}{Q_{2}}=\frac{T_{1}}{T_{2}}\) \(\frac{\mathrm{Q}+1200}{\mathrm{Q}}=\frac{900}{300}\) \(\mathrm{Q}+1200=3 \mathrm{Q}\) \(Q=600 \mathrm{J}\)
