Solids have a fixed volume and are rigid.
Liquids have a fixed volume but they are very flexible, i.e. they take the shape of whatever container you put them into. Gases do not have a fixed volume. Gases will fill any space that they are allowed into. In a liquid state, molecules touch one another and interact with one another. In a gas state, molecules will rarely bump into one another they are too far apart.
