The melting point of a substance is an example of?

Melting point of a substance is the temperature at which a substance changes from a solid to a liquid. A change of state like melting is a physical change because it doesn’t alter the identity of the substance. In other words, melting point is a physical property because you can determine an object’s melting point without changing the substance. For example, when a substance like ice melts into water, the identity of the substance doesn’t change; the substance is water before and after the physical change. On the other hand, flammability is a chemical property because burning an object is a combustion reaction that leads to the creation of new substances. When you burn a piece of wood, it reacts with oxygen in the air to produce heat, light, carbon dioxide, and water vapor.
