The efficiency of the heat engine can be defined as:
Correct answer: D. 1- Q2/Q1
- A. Q2 - 1/Q1
- B. Q2 + 1/Q1
- C. Q2 + Q1
- D. 1- Q2/Q1
Explanation
The efficiency of a heat engine is typically defined as the ratio of the useful work output to the heat input. It is a measure of how well a heat engine converts the input heat energy into useful work.The efficiency of a heat engine is represented as : n = 1- Q2/Q1.

About First Law of Thermodynamics
The first law relates heat supplied, work done and the change in internal energy through energy conservation. Problems use sign conventions and apply the law to isothermal, adiabatic, isobaric and isochoric processes. Internal energy is a state function, while heat and work depend on the path followed.
