The quantity of heat required to raise the temperature of one mole of a substance through 1 K is called:
Correct answer: B. Molar specific heat
- A. Carnot engine
- B. Molar specific heat
- C. Kinetic specific heat
- D. General gas law
- E. Boyle's law
Explanation
Specific heat is the amount of heat needed to raise the temperature of one kilogram of mass by 1 degree. The molar heat capacity is the heat capacity per unit amount (SI unit: mole) of a pure substance, and the specific heat capacity often called simply specific heat, is the heat capacity per unit mass of material. Option B is correct.

About Molar Specific Heat of a Gas
Molar specific heat is the heat required to raise the temperature of one mole of a gas by one kelvin, expressed through Q = nCΔT. Questions compare the constant volume value Cv with the constant pressure value Cp, apply the ideal gas relation Cp − Cv = R, and identify how the thermodynamic process affects heat capacity.
