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

Change of state is the process whereby a substance changes its state of matter from one form to another as as result of heat changes.

In the graph shown above, water exists in three states at different points.

  • Water exists as a solid at A
  • Water exists as a liquid at B
  • Water exists as a gas at C.

Therefore, the phase changes that occur in water is from a solid at A to a liquid at B, and from liquid a B to gas at C.
