A liquid has a particular volume but it doesn't have a definite shape. Liquid takes the shape of the container in which it is kept.
The inter-molecular forces in case of a liquid are not as strong as in solids and hence a liquid is not held together tightly. Thus, the liquid takes up the shape of the container in which it is kept.

In a solid, the particles are held together by strong intermolecular forces between them and hence there is very little scope of movement for the particles in solid. So, kinetic energy of solid is very low.

On heating solids, intermolecular attraction between the particles decreases as the particles gain energy to move randomly.

On heating liquids, intermolecular space between molecules increases as the particles gain enough kinetic energy to overcome the force of attraction.

On heating solids, the intermolecular space between the molecules increases due to the movement of molecules randomly.

Change of solid state into liquid state is known as fusion.

The temperature at which particles slow down and convert into a solid is known as solidification point.

On heating a liquid, heat absorbed by its molecules is absorbed and stored in the form of potential energy.

The solid formed by directly cooling a gaseous substance through a process of sublimation is known as sublimate.

On heating liquids, intermolecular attraction decreases as the particles gain enough kinetic energy to overcome the attraction.
