HUL UU 27) The efficiency of a heat engine is the ratio of ​

Answer 1

Answer:

The efficiency of a heat engine is defined as the ratio of work done by the heat engine to heat absorbed per cycle. If a heat engine absorbs Q1 amount of energy from the source and dissipates Q2 amount of energy to sink, the efficiency η, is given by, η=Q1Q1−Q2=1−Q1Q2.
