What is the term for a substance undergoing a chemical change?

What happens to matter when it undergoes a physical and chemical change?
A chemical change cant be undone and a new substance, so in other words you cant reverse the effects and in the end you get ashes.

Is sand flowing through an hour glass an chemical or physical change?
It is not really a change, at all. Sand is moving from one spot to another. If it truly had to be categorized, I would put it under a physical change. A physical change would be a change in an object you can see with your eyes. However, the chemical makeup of that object does not change. In other words, no new chemical is formed. For example, water may freeze or evaporate, but the chemical makeup of water, no matter what state it is in, is H2O. A chemical change would would result in the formation of one or more new chemicals. For example, burning paper is a chemical change. You have paper and fire, and when you burn the paper up, it gives off CO2, and charred paper, which is different from regular paper.
