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.

Condensation takes place when the atoms or molecules come together and clump due to increased inter-molecular attraction.

At boiling point, the particles of liquid  get converted into a gas.

On cooling gases and liquids, temperature falls intermolecular attraction increases intermolecular space between molecules decreases.
