Water: on heating to 1000 C it start boiling and converted to water vapor.
Again water when cooled to 00 C freezes to solid ice.
Metallic iron when heated to 2750 0 C is in molten state and when cooled to 15350 C freezes to solid iron metal. The phenomena is called “change of state” and the changes are melting, freezing, boiling.

umm.. it's 100°C sir, not 1000°C boiling point of water is 100°C :))

The two methods that can change the state of matter are as follows:
• Melting: When a solid is heated, its temperature rises until it reaches its melting point.
If you add some additional heat to the material, it will not raise the temperature until all of the material is melted.
• Boiling: When a liquid is heated, its temperature rises until it reaches its boiling point.
If you continue adding heat to the liquid, the particles become even more active, causing the liquid to turn into a gas.
This state change is called boiling or vaporizing.
