Which one is correct:
Correct answer: A. Cp = Cv
- A. Cp = Cv
- B. Cv > Cp
- C. Cv < Cp
- D. Cv ≥ Cp
Explanation
For an ideal gas, during an isochoric (constant volume) process, the specific heat at constant volume (Cv ) is equal to the specific heat at constant pressure (Cp ). Therefore, Cp =Cv .

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.
