Efficiency of the Carnot engine:
Correct answer: D. None of these
- A. Depends upon T and Ta
- B. Depends upon the working substance
- C. Is 100% if T2 =0K
- D. None of these
Explanation
The efficiency of the Carnot engine depends only on the temperatures of the hot and cold reservoirs, T and Ta , respectively. It is given by the formula η=1−Ta/T .

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.
