If two bodies have the same temperature, the rate of heat transfer between them is:
Correct answer: B. Zero
- A. Infinite
- B. Zero
- C. Double the temperature
- D. None of these options are correct
Explanation
Option B is correct since if the temperatures of the two bodies are equal, there will be no transfer of heat energy as heat is an energy that flows from a hotter body to a colder body.Option A is incorrect since it states that the rate of transfer will be infinite which is the case in a vacuum.Option C is incorrect since it states that the rate of heat transfer will be double the temperature which is not the case.Option D is incorrect since it states none of these, which is not the case.

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.
