What is melting physical proreties of wax but frammabillty is a change propeties?
Melting is a physical property because it only changes the physical state of the substance, such as wax, but does not change its physical or chemical properties. This is because melting is not a chemical reaction. Flammability, however, is a chemical property, and when a substance burns, that is a chemical reaction, and the physical and chemical properties of the products will be different than the reactants (starting substances).
