Question

Define efficiency of heat engine? How does the efficiency of heat engine can be increased?​

Answer 1

Efficiency. The efficiency of a heat engine relates how much useful work is output for a given amount of heat energy input. In other words, a heat engine absorbs heat energy from the high temperature heat source, converting part of it to useful work and delivering the rest to the cold temperature heat sink.

Answer 2

A) Define efficiency of heat engine?

Answer : Heat engine is a device that performs the conversion of heat energy to mechanical work through cyclic process. The efficiency of a heat engine is defined as the ratio of work done by the heat engine to heat absorbed per cycle.

B) How does the efficiency of heat engine can be increased?

Answer : the efficiency of the heat engine can be increased by decreasing the temperature of the cold sink or increasing the temperature of the hot source.
