For the successful operation of the heat engine, which condition should be met.
Correct answer: D. both (a) and (b)
- A. cyclic process
- B. operated at certain temperature difference
- C. petrol must be used
- D. both (a) and (b)
Explanation
A heat engine works by utilizing a cyclic process, where it continuously operates in a repeating sequence.Additionally, a heat engine relies on a temperature difference between its heat source (where it absorbs heat) and its sink (where it releases heat) to function efficiently

About Thermal Equilibrium and Heat
Thermal equilibrium means that bodies in contact have the same temperature and no net heat flows between them. The topic distinguishes heat from temperature, uses the zeroth law of thermodynamics, and covers heat transfer, specific heat capacity, thermal expansion and the conditions for reaching equilibrium.
