Physical property is the substance inherent property. To get this no need of the change in chemical state of the substance.
Chemical property are the property of the substance, which corresponds to chemical nature of the molecule i.e. to show chemical property, a new chemical species is generated.
Physical changes is the process of changing one Physical state to other physical state .
Chemical changes is the process of changing the substance chemical identity.
