Answer 2

Given: A heat engine operates between a heat source at 700 K and a heat sink at 300 K.

To find: We have to find the maximum efficiency of the engine.

Solution:

According to the Carnot cycle, the efficiency of an engine can be determined by the below formula-

$n=1-\frac{T_c}{T_h}$

Where n is the efficiency of the heat engine.

${T_h}$ is the heat of the source=700K.

${T_c}$ is the heat of the sink=300K.

Putting the values in the formula we get-

$n = 1 - \frac{300}{700} \\ n = 1 - 0.4285 \\ n = 0.57$

So, the efficiency of the engine will be 0.57×100=57%.

The efficiency of the heat engine is 57%.
