Heat capacity of a substance is infinite. It means --------
Correct answer: C. No change in temperature
- A. Heat is given out
- B. Heat is taken out
- C. No change in temperature
- D. Heat is first given out and then taken out
Explanation
Option C is correct.The heat capacity is the amount of heat required to raise the temperature of an object or substance by one degree. ΔQ=nCp ΔT So, ΔT= nCp ΔQ If heat capacity i.e. C p is infinite, ΔT is negligible.

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.
