Effect of Change of Temperature

Heating and cooling matter are the main ways to change matter from one state to another. We can convert a solid into a liquid by applying heat on it. Similarly a liquid can be changed into a gas by heating. The reverse is also true when a gas is deprived of some of its heat energy it becomes a liquid. When a liquid is further deprived of its heat energy it will turn into a solid.


Freezing is the process of cooling a liquid to the temperature where it turns solid. The temperature at which liquid becomes solid is called freezing point.

Melting of ice

Take a funnel and add few ice cubes in it. A thermometer is fixed to an iron stand.The ice melts. Melting is the process of conversion of a solid to a liquid at a temperature where it becomes liquid. The temperature at which solid turns liquid is called melting point.
