-A physical change is any change in matter that involves the substance going from one physical state to another. The reference to a physical state involves solids, liquids, and gases. When a substance undergoes a physical change it does not lose its original properties when changing from one phase to another.
-Examples of physical changes include;
Ice melting involves a change from a solid to a liquid and the substances maintain the properties of water because the molecules never change.
Water boiling is a physical change as water molecules vibrate faster, they enter the gas phase and become water vapor.
