1.	For a Carnot engine, the source is at 500K and the sink at 300K.What is efficiency of this engine? A) 0.2 B) 0.4 C) 0.6 D) 0.3
Answer» Answer: B) 0.4 Explanation: Given that, T₁= 500K, T₂=300 K \(\eta=\frac{T_1-T_2}{T_1}= \frac{500-300}{500}=\frac{200}{500}=0.4\)

Answer»

Answer: B) 0.4

Explanation:

Given that, T₁= 500K, T₂=300 K

\(\eta=\frac{T_1-T_2}{T_1}= \frac{500-300}{500}=\frac{200}{500}=0.4\)
