Question

Gases have lower densities compared to solids ke liquids.give a reason

Answer 1

Due to low intermolecular forces b/w gas particles the volume of gases is high as compared to solids and liquids.

Since, Density is inversely proportional to volume.

hence, gases have low density.

Answer 2

A gas usually has much lower density than a solid or liquid. ... The molecules or atoms in a gas are much further apart than in a solid or a liquid. Gas molecules or atoms are usually flying around at very high speeds, occasionally bouncing off each other or the walls of the container the gas is in.
