Explanation: Matter is classified into three main categories:

a) Solids: have fixed size and volume . They have strongest forces of attraction.

b) Liquids: have fixed volume but no fixed shape. They acquire the shape of the container. They have intermediate forces of attraction.

c) Gases: have no fixed shape and no fixed volume. They occupy complete volume of the container. They have weakest forces of attraction.
