Q. Vessel $A$ is filled with hydrogen while vessel $B,$ whose volume is twice that of $A,$ is filled with the same mass of oxygen at the same temperature. The ratio of the mean kinetic energies of hydrogen and oxygen is
A) $16\ :1$
B) $1\ :8$
C) $8\ :1$
D) $1\ :1$
Explanation
(d) Average kinetic energy $E = \frac{f}{2}kT$
Sinec $f$ and $T$ are same for both the gases so they will have equal energies also
