Change of state occurs when heat is supplied or removed from a substance.

<h3>What is change of state?</h3>

Change of state refers to the changes that occur when a substance changes from one physical state to another due to changes in its temperature.

It is also known as phase change.

Phase Change can also be defined as change from one state to another without a change in chemical composition.

Some of the phase changes include:

  • Freezing: when liquid changes to solid
  • Condensation: when gas changes to liquid
  • Melting: when solid changes to liquid
  • Evaporation: when liquid changes to gas

The other terms associated with phase change include:

  • Freezing point: temperature wherein a liquid solidifies
  • Melting point: the temperature at which solid turns into a liquid.
