A helium atom is two times heavier than a hydrogen molecule. At `298 K`, the average kinetic energy of a helium atom is

A

two times that of hydrogen molecule

B

same as that of hydrogen molecule

C

four times that of hydrogen molecule

D

half that of hydrogen molecule

Text Solution

Verified by Experts

The correct Answer is:

B

Average KE depends only on temperature and does not depends upon the nature of the gas.
