PHYSICAL CHANGE - EXAMPLE
When the shape, size, appearance or state, of a substance is altered, but its chemical composition remains same a physical change of matter takes place. No new substance is formed. It is usually a change, which is reversible that is, by reversing the process the original substance can be obtained. During melting of ice, it converts into water. It is a physical change as composition is not changed.
