MHT CET 2022 Physics question

In a thermodynamic system, working distance is an ideal gas. Its internal energy is in the form of

(A)neither kinetic nor potential energy.
(B)both kinetic and potential energy.
(C)only potential energy.
(D)only kinetic energy.Correct

Answer: (D)

Solution

In the kinetic theory an ideal gas consists of point molecules with no intermolecular forces, so there is no intermolecular potential energy. The internal energy is therefore entirely the random translational (and rotational/vibrational) kinetic energy of the molecules, \tfrac$
