During an adiabatic process pressure of gas is found to be proportional to the cube of its temperature. The ratio of Cp/Cv is
Correct answer: D. 3/2
- A. 4/3
- B. 2
- C. 5/3
- D. 3/2
Explanation
PV=nRT P∝T^3 P∝(PV)^3 k= P^2 V^3 PV^3/2 ; k = 3/2

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.
