What is the difference between the physical properties and the chemical properties of a substance?

Chemical properties: may only be observed by changing the chemical

Physical properties: An aspect of matter that can be observed or measured without changing it

The difference between physical and chemical properties:

Physical properties are what you can see or feel, for instance, color or texture of an object whilst chemical properties describe how a substance behaves during a chemical reaction (note that we cannot see it, the substance has to actually change its form for us to be able to see the chemical properties).
