Define: Inter-molecular force:
Inter-molecular force: The force of attraction between molecules is called intermolecular force.
Anything that occupies some space and has some mass is called matter.
Matter exists in three states:
Solid – They have strong intermolecular forces of attraction between the particles.
Liquid - They have the less intermolecular force of attraction as compared to solids in between the particles of liquids.
Gas - They have very negligible intermolecular forces of attraction in between the particles.
