Condensation

 When the freely flowing particles of steam touch a cold surface it condenses.
 While cooling, the movement of the particles slows down and becomes less free to move and
change from gas to liquid.

4. Freezing: A change of state from liquid to solid state is known as Freezing.
Example:

Freezing

 During this process of freezing, the particle movement slow down even more.
 It gets close together to make a rigid shape, thus forming solid shape.
 Freezing point is the temperature at which a liquid turns into a solid when cooled.
