Helium atom is two times heavier than a hydrogen molecule. At 298 K, the average kinetic energy of a helium atom is
Text Solution
Verified by ExpertsThe correct answer is:
B
Same as that of a hydrogen molecule Average kinetic energy per molecule or atom ( 
where 
is 
) depends only on the temperature and does not depend upon the nature of the gas. Hence average kinetic energy of helium atom is same as that of a hydrogen molecule.
