Answer 2

Answer:

Here is the answer for your question:

A matter may exist in three forms or states named as:

Solid ; Liquid ; Gas.

=> A Solid state is a state in which matter is characterised by having definite shape, distinct boundaries, rigidity,incompressibility and fixed volume.

=>A Liquid state shows fluidity, low compressibility and

no definite boundaries, volume or shape.

=>A Gaseous state low density, high compressibility, equal pressure in all directions,mix evenly, intermolecular force, and no shape, volume of a container.

•••Therefore,The inter-conversion of these three forms or states of matter is called Change of state.

•••Melting is the change that occurs when a solid

changes into a liquid at atmospheric as the temperature

increases.

•••Freezing is the change that occurs when a liquid changes into a solid as the temperature decreases.
