Question

Why gases have much lower densities than liquids and solids?

Answer 1

Answer:-

Since molecules in solid are more closely packed as a result of much stronger internuclear forces .

This results in more mass present in the same volume if solids than of liquids.

Density=mass/volume

Hope this helps:)

Answer 2

Gas has a lower density than liquids because it is not compressed as tightly as liquids meaning there are fewer atoms per unit of volume. In a liquid, atoms are free to move but remain closely associated, while in a gas, atoms have lots of free space between one another
