Chemical substance

From Simple English Wikipedia, the free encyclopedia
Water and steam are two different forms of the same chemical substance

A chemical substance is any material with a known chemical composition.[1] For example, water has the same properties and the same ratio of hydrogen to oxygen whether it came from a river or was made in a laboratory. Typical chemical substances found in the home include water, salt and bleach. Generally, substances exist as a solid, a liquid, or a gas, and may change between these phases of matter when there are changes in temperature or pressure.
