The specific heat of a gas in an isobaric process is:
Correct answer: D. Cₚ
- A. Zero
- B. Infinite
- C. Cᵥ
- D. Cₚ
Explanation
In an isobaric process, pressure is constant, and the specific heat capacity used is Cp (specific heat at constant pressure), which accounts for both internal energy change and work done.

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.
