Question

What can you say about particles motion in gases?

(a) only vibratory

(b) very slow

(c) both vibratory and irregular

(d) too Rapid and random

This question was addressed to me in final exam.

I would like to ask this question from States of Matter in chapter States of Matter of Chemistry – Class 11

Answer 1

Right answer is (d) too Rapid and random

The best explanation: A particle’s motion in the gaseous state is too rapid and random while in solids it’s restricted to vibratory motion and in liquids, it’s very slow. This is one of the very basic properties of substances in the gaseous state.
