Detailed explanation-1: -Melting butter doesn’t change the identity of the butter, so this is a physical change.
Detailed explanation-2: -Melting butter in a pan is known as an example of a physical change. In this process, no new compound of different composition gets formed. Also, by melting butter, the butter gets converted from its solid to the liquid state, which includes the change in physical properties.
Detailed explanation-3: -No chemical bonds are broken or formed in melting butter, so it is not a chemical change. The melting process is only a physical change, the change of state from solid to liquid.
Detailed explanation-4: -But when butter melts, it goes from a solid state to a liquid state. That’s a physical change. It’s easily reversible if you return the butter to a cold place where it solidifies again.
