(a) Compare the properties of solids, liquids, and gases in tabular form.(b) Give two reasons for saying that wood is a solid.


(a) Comparative study of the properties of solids, liquids, and gases is given below:

SolidLiquidGas
Solids have a definite shape and volume.Liquids have fixed volume but take the shape of the container in which it is kept.Gases have neither a fixed shape nor fixed volume.
It cannot be compressed.It cannot be compressed much.It can be compressed easily.
It has a high density.Its density is moderate to high.

It has a very low density.

The force of attraction (intermolecular) between the particles is very strong.
The intermolecular force of attraction is weaker than solids.
The intermolecular force of attraction is the weakest.
The space between the particles (intermolecular) of solids is negligible.
They have considerable intermolecular space between the particles.
The intermolecular space between gas particles is large.

(b) Wood is solid because it has a fixed shape and volume, and it is rigid and cannot be compressed.
