The quantity measured in J/mol.K is
Correct answer: C. Molar specific heat
- A. Specific heat
- B. Thermal conductivity
- C. Molar specific heat
- D. Latent heat
Explanation
Molar specific heat is the heat needed to raise the temperature of one mole by one kelvin, so it is measured in J per mol K. Specific heat uses J per kg K, thermal conductivity uses W per m K and latent heat uses J per kg.

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.
