Chemical changes happen when chemical reactions close chemical reaction When chemical bonds are broken and made between atoms, so that new substances (compounds or elements) are made. occur ...
May 7, 2019 · Since the chemical identity of the matter in question is unchanged, this process represents a physical change. Thus melting point is a physical property. On the other hand, flammability is a chemical property of matter because the only way to know how readily a substance ignites is to burn it. In the chemical reaction for combustion, the ...

Physical. Chemical properties are properties that can be observed or measured when a substance undergoes a chemical change. Physical properties are properties that can be observed without bringing a chemical change. A chemical reaction needs to be conducted to show the property. No chemical reaction is needed here.
