Let

\overline{{v}}, {v}_{\mathrm{rms}}

and

{v}_{{P}}

respectively denote the mean speed, r.m.s. speed, and most probable speed of the molecules in an ideal monatomic gas at absolute temperature T. The mass of a molecule is

m

, then which of the following is correct?

View answer and explanation

Correct option: C

{v}_{{p}} < \overline{{v}} < {v}_{\text {r.m.s. }}

Option C is correct because the most probable speed is less than the average speed, which is less than the root-mean-square speed.

Assertion: The pressure exerted by an enclosed ideal gas does not depend on the shape of the container.
Reason: The pressure of an ideal gas depends on the number moles, temperature and volume of the enclosed If
