Define heat engine.
Suppose a person wants to increase the efficiency of the reversible heat engine that is operating between 100°C and 300°C. He had two ways to increase efficiency.
- By decreasing the cold reservoir temperature from 100°C to 50°C and keeping the hot reservoir temperature constant
- by increasing the temperature of the hot reservoir from 300°C to 350°C by keeping the cold reservoir temperature constant.
