When a substance dissolves it undergoes a chemical change physical change molecular change?
you should know the answer to that cause i don't
Is bending a metal wire a physical or chemical change?
It's a physical change, because bending a wire doesn't affect the chemical makeup of it.
What are the differences between a chemical and physical change?
A physical change doesn't change the molecular properties of a substance. Some examples of physical changes include tearing paper, or the evaporation of water. A chemical change does change the molecular properties of a substance. For example, if you burn wood you get leftover carbon, and CO2 is also released; no longer does the wood have the same molecular properties or structure.
Are physical changes chemical reactions?
No, physical changes normally refer to changes other than chemical reactions. If you have a loaf of bread and cut it in half, that is a physical change but not a chemical change. If you eat the bread and digest it, that is a chemical change.
Is a glass breaking a chemical change?
A chemical change is when the molecules of an object / solution are changed. A physical change is when the object / solution is altered without molecular change. Breaking glass is a physical change.

What is an xaple of physical rather tham a chemical change?
A chemical change occurs when molecular structure is altered. Ex: oxidation A physical change is any sort of change that occurs without affecting the molecular structure. Ex: freezing
A piece of solid gold that changes from a solid to a liquid is a physical or chemical change?
physical: it's a change of state, it does not change the chemical makeup: molecular, atomic
