Question

The internal energy of an ideal gas depends on:

Solution

Correct option is

Temperature

Intermolecular attraction is zero in an ideal gas. Hence, internal energy of an ideal gas is wholly kinetic. As kinetic energy depends on temperature only, hence internal energy of an ideal gas depends only on its temperature.
