Assertion : Internal energy of an ideal gas depends only on temperature and not on volume.
Reason : Temperature is more important than volume.

Options

A. If both Assertion and Reason are true and Reason is the correct explanation of Assertion.
B. If both Assertion and Reason are true but Reason is not correct explanation of Assertion.
C. If Assertion is true but Reason is false.
D. If both Assertion and Reason are false.

Answer

C

Explanation

In an ideal gas, we assume that intermolecular forces are zero. No work is done in changing the distance between the molecules. Therefore, internal energy is only kinetic and not potential. Therefore, internal energy of an ideal gas depends only on temperature and not on volume.
