Oxygen and hydrogen are at the same temperature T. What is the ratio of kinetic energies of oxygen molecule and hydrogen molecule when oxygen is 16 times heavier than hydrogen ?

A

`16`

B

`4`

C

`1`

D

`1//4`

Text Solution

Verified by Experts

The correct Answer is:
C
`(K.E.)_(O_(2))/((K.E)_(H_(2))) = ((5)/(2) kT)/((5)/(2)kT) = 1`
