The heat required to raise the temperature of body by 1 K is called___________?
Correct answer: B. thermal capacity
- A. specific heat
- B. thermal capacity
- C. water equivalent
- D. None of the above
Explanation
The heat required to raise the temperature of an entire body by 1 K is its heat capacity, also called thermal capacity, with units J K^-1. Specific heat is the heat required per unit mass, so option b is correct. Students may choose a because it contains the word heat, but specific heat must refer to a particular mass, usually 1 kg or 1 g.

About System, Surroundings and State Functions
A system is the part of the universe under study, while everything outside it is the surroundings; the boundary separates them. State functions such as pressure, temperature, volume, internal energy and enthalpy depend only on the state, unlike heat and work, which depend on the path taken.
