Heat capacity is defined as _ required to change the temperature of substance by_
Correct answer: B. Heat, 1 degree C
- A. Momentum, 1 degree C
- B. Heat, 1 degree C
- C. Heat, 2 degree C
- D. Work, 2 degree C
Explanation
Heat capacity is defined as the amount of heat energy required to raise the temperature of a given quantity of matter by one degree Celsius. Heat capacity for a given matter depends on its size or quantity and hence it is an extensive property. The unit of heat capacity is joule per Kelvin or joule per degree Celsius.

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.
