Diatomic molecules of a gas have _ K.E.
Correct answer: D. All
- A. Translational
- B. Vibrational
- C. Rotational
- D. All
Explanation
Diatomic molecules possess translational kinetic energy (related to their overall motion), vibrational kinetic energy (due to the vibrations of the bonds between the atoms), and rotational kinetic energy (due to their rotation). Therefore, they possess all three types of kinetic energy.

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.
