Q. At what temperature, the mean kinetic energy of $O_{2}$ will be the same for $H_{2}$ molecules at $- 73℃$
A) $127℃$
B) $527℃$
C) $- 73℃$
D) $- 173℃$
Explanation
(c) Mean kinetic energy of molecule depends upon temperature only. For $O_{2}$ it is same as that of $H_{2}$ at the same temperature of $- 73℃$
