What are the difference between physical and chemical property ?

Chemical properties can be observed or measured when a substance undergoes any type of changes chemically while Physical properties can be observed without changing anything.

In chemical property, chemical reaction is conducted to show the property of the substance while in physical property No chemical reaction occur.

Chemical properties related to chemical bonds while Physical properties do not have such a relationship.

Chemical properties include radioactivity, toxicity, flammability, heat of combustion,  etc. while physical properties include Molecular weight, boiling point, melting point, freezing point, volume, mass, length, density shape, solubility, etc.
