The mass of an oxygen molecule is about 16 times that of a hydrogen molecule. At room temperature the rms speed of oxygen molecules is v. The rms speed of hydrogen molecules at the same temperature will be:
Options:
Answer:
C
Solution:
$v_{r m s} \propto \frac{1}{M}$ , so hydrogen is
$16 = 4$ times faster. C.
