Why is a phase change like solid to liquid a physical change?

Melting, the phase change from a solid to a liquid, is considered a physical change rather than a chemical change because when the phase change takes place, the substance that was melted does not change its chemical composition, and the process could be reversed to get the original condition of the substance by freezing (liquid-solid).

Is there a liquid that will change color when it comes in contact with gold?

I doubt it. Color-change is an indication of a chemical reaction. Gold, however, is generally non-reactive (although highly conductive), which is why it doesn't tarnish or rust. Since I cannot think of another chemical gold reacts easily with, I'm giving a tentative "no" to your question.


Properties seen when one substance changes to another are known as?

there are two types of change. the first one is the physical change. the form or appearance of the substance is change but the chemical properties of the substance is not changed. example, water evaporates into the air, that is a physical change because from liquid, water changes into gas but it then comes back to water as rain. the other one is chemical change wherein the chemical properties of the substance is changed. example is burning of wood. wood is burned and turned into charcoal. the chemical properties of wood is different from the chemical properties of charcoal and charcoal is another substance.
