Inter-conversion of States of matter
The states of matter are inter-convertible by changing the conditions of temperature and pressure. On heating, a solid usually changes to a liquid, and the liquid on further heating changes to gas or vapour. In the reverse process, a gas on cooling liquifies to a liquid and the liquid on further cooling freezes to the solid.
