Question
Helium atom is two times heavier than a hydrogen molecule at 298 k, the average kinetic energy of helium is :
Options
A.two times that of hydrogen molecule
B.same as that of the hydrogen molecule
C.four times that of a hydrogen molecule
D.half that of a hydrogen molecule
Solution
Average K.E. = 
RT and T is constant 298 K
∴ K.E. is same for all gases at same Temperature.
RT and T is constant 298 K∴ K.E. is same for all gases at same Temperature.
