Effect of Change of Temperture
By increasing the temperature (by heating), a solid can be converted into liquid state; and the liquid can be converted into gaseous state (or vapour state). And by decreasing the temperature (by cooling), a gas can be converted into liquid state ; and a liquid can be converted into solid state. These points will become more clear from the following discussion.
