Answer:
Interconversion of matter refers to change of one state to another. It is a process by which matter changes from one state to another and back to original state , without any change in its chemical composition. Solid can be converted into liquids by heating .
It is because substance makes use of latent heat of fusion to overcome force of attraction between particles of solid to change into liquid during melting and latent heat of vaporization to overcome force of attraction between particles of liquid to change into vapours during boiling.
There is no space between the individual particles, so they cannot pack together. The kinetic-molecular theory explains why gases are more compressible than either liquids or solids. Gases are compressible because most of the volume of a gas is composed of the large amounts of empty space between the gas particles.
In a liquid, the particles are still in close contact, so liquids have a definite volume. However, because the particles can move about each other rather freely, a liquid has no definite shape and takes a shape dictated by its container.
