Can Matter Changes its State

Matter changes from one state to another by heating, cooling or by other methods. On heating the intermolecular space between the molecules increases and the intermolecular force decreases in solids and liquids and then changes the state to liquid in case of solid and gas in case of liquid During the cooling process the intermolecular space decreases whereas intermolecular force decreases between the molecules The matter changes from one state to another in the following ways:-

1. From solid state to liquid on melting
2. From liquid to gaseous state by boiling
3. Gas to solid on sublimation.
4. Liquid state to solid state by undergoing freezing.
5. From gaseous to liquid state on condensation.

Here,is the video to know a brief study of why matter change its state

Why changes occur?

Changing states of matter occur when matter loses or absorbs energy. When a substance absorbs energy; the atoms and molecules move more rapidly and this increased kinetic energy pushes particles far enough that they change form.
