Some of the properties of solids, liquids and gases are listed ahead.

Separate these properties for the three states of matter.

Definite volume, least closely packed, can flow downwards, highly compressible, highly rigid, diffuse slowly.

Arrange the following:

(a) Solids, liquids and gases in increasing order of the constant motion of their particles.

(b) Copper metal, water vapour and milk in decreasing order of their intermolecular forces of attraction.

What is meant by interconversion of matter?

State two factors responsible for the change of state of matter.
