In case of boiling, the liquids can slowly change into gaseous form at a temperature below their boiling point.

Gases expand to a large extant when heated.

The density of liquids is relatively more than solids.

Solids do not diffuse when they are kept in contact with one another.

Liquids have only one free surface.

During freezing the temperature continues to fall.

Molecules of gas have least kinetic energy.

During interconversion of matter, mass remains constant.

A decrease in pressure lowers the boiling point of liquid.

During sublimation, the substance must be heated.

Intermolecular force in case of solids is maximum.

Gases have any number of free surface.
