Question
Helium atom is two times heavier than a hydrogen molecule. At 298 K, the average kinetic energy of a helium atom is :
Options
A.Two times that of a hydrogen molecule
B.same as that of a hydrogen molecule
C.four times that of a hydrogen molecule
D.half that of a hydrogen molecule
Solution
Average k. E. = 3/2 KT and it depends on temperature only and not on the nature of gas. So both gas have same
