If a gas expands at constant temperature...

If a gas expands at constant temperature, it indicates that

A

kinetic energy of the molecules decreases

B

pressure of the gas increases

C

kinetic energy of the molecule remains the same

D

number of molecule of the gas increases

Text Solution

Verified by Experts

The correct Answer is:
C
As kinetic energy of a gas depends only on temperature, if temperature is kept constant, kinetic energy remains the same.
