A physical property is an aspect of matter that can be observed or measured without changing it. Examples of physical properties include color, shape, size, molecular weight and volume.
A chemical property on the other hand may only be observed by changing the chemical identity of a substance, that includes whether it can undergo a certain chemical change
.
Physical property is defined as the property of a substance which becomes evident during physical change in which there is alteration in shape, size etc. No new substance gets formed during physical change. Example: Melting point
Chemical property is defined as the property of a substance which becomes evident during chemical change in which a change in chemical composition takes place. A new substance is formed in these reactions. Example: Reactivity with other substances
Thus property of matter that can be identified without changing the identity of the substance is physical property.
