In general, solids have a fixed volume because the atoms arrange themselves in a way that resists a change in volume. This may sound simple, but it is, in fact, a simple idea. The atoms form up as the substance changes state from a liquid to a solid, and whatever shape they assume when they give up the energy of melting is the shape they take. The issue is one of change of state after a change of thermal energy.

A solid has a definite volume because the molecules are tightly packed and whether it is an ice cube and turns into a liquid by melting it still is the same amount unless you are adding on to it.

A strong inter-molecular force of attraction exists within the solid. The molecules are tightly packed and can't move. Hence they are said to have a definite volume.

becoz the atoms are held together & there is no space between them.
