The flow of heat energy from the hot to the cold body is a/an _ process.
Correct answer: B. Irreversible
- A. Reversible
- B. Irreversible
- C. Depends on the conditions
- D. Conduction process
Explanation
In heat conduction, heat is transferred from one place to another. This process is not reversible. Heat can be transferred through radiation also. It is also irreversible.

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.
