Give reasons for the following:
(b) Gases have lower density compared to that of solids or liquids.

Open in App

Solution

The number of molecules per unit volume in a gas is very small as compared to solids and liquids.

Gases have large inter-molecular space between their molecules.

Therefore, gases have very low density
