Unit of molar specific heat is same as that of:
Correct answer: B. General gas constant
- A. Entropy
- B. General gas constant
- C. Internal energy
- D. Pressure
Explanation
Unit for molar specific heat (C) is J/mol·K. The unit for the general gas constant (R) is also J/mol·K, as seen in the ideal gas law. Therefore, they share the same units.

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.
