The specific heat of a substance depends on:
Correct answer: C. Its material properties
- A. Its mass only
- B. Its temperature only
- C. Its material properties
- D. Its volume only
Explanation
Specific heat capacity is an intrinsic property of a material, varying based on its chemical composition and structure, not on mass, volume, or temperature alone.

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.
