OVERVIEW A physical property is a characteristic that can be observed and measured without changing the identity and composition of the substance. Examples of physical properties are color, melting point, and boiling point. Physical properties are very important because these help chemists in identifying substances. For example, a clear, colorless liquid observed to boil at 100 and freeze at OE would definitely be water. Water undergoes physical change wherein its physical appearance changes but its composition remains unchanged. I. ОВIЕСTIVES 1. To be able to determine the physical properties of matter. III.
