A chemical substance is a material with a specific chemical compound.
A common example of a chemical substance is pure water; it has the same properties and the same ratioof hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Some typical chemical substances are diamond, gold, salt (sodium chloride) and sugar (sucrose). Generally, chemical substances exist as a solid, liquid, or gas, and may change between these phases of matter with changes intemperature or pressure. Chemical reactions convert one chemical substance into another.
Forms of energy, such as light and heat, are not considered to be matter, and thus they are not "substances" in this regard.

Write 3 differences between chemical and physical change?
Okay now here goes in a physical change no chemical reaction takes place. in chemical change chemical reactions take place. A physical change is reversible but a chemical change is not.In a physical change no new substance is formed(A+B=B) in a chemical change new substances are formed(A+B=C)
Do chemical changes take place when a mixture is made?
No!chemical changes do not take place when a mixture is made.The constituent substances of the mixture retain their own chemical composition.Thus only physical changes take place.
