Assertion : Internal energy of an ideal gas does not depend upon volume of the gas.
Reason : This is because internal energy of ideal gas depends only on temperature of gas.

Options

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

Answer

B

Explanation

Internal energy of an ideal gas does not depend upon volume of the gas, because there are no forces of attraction/repulsion amongst the molecules of an ideal gas.
Also internal energy of ideal gas depends on temperature.
