Describe three physical changes water can go through

1. Ice melting involves a change from a solid to a liquid and the substances maintain the properties of water because the molecules never change.

2. Water boiling is a physical change as water molecules vibrate faster, they enter the gas phase and become water vapor.

3. Dissolving sugar in water is a physical change. The solid sugar never loses its properties, the molecules become separated by water and the sugar can easily be recovered by evaporating the water.
