A bellows-type thermostat typically uses a volatile liquid or gas as the chemical that causes pressure changes. Common substances include refrigerants or specialized liquids that expand and contract with temperature fluctuations. As the temperature changes, the substance changes its phase or pressure, causing the bellows to expand or contract, which activates the thermostat mechanism to regulate temperature.
A reaction between two substances or the decomposition of a substance are chemical changes.
After chemical reactions new substances are obtained.
The ability to react with other substances is a chemical property.

In order to defend our body, macrophages release chemicals that are toxic to eliminate diseases and harmful foreign bodies. They also secrete growth factors that are essential in healing wounds.
The chemical properties of an object show what a chemical change did to that substance.

Substances that undergo chemical change are called reactants.

A chemical is always a chemical, by definition. Chemicals are substances with a distinct structure that can undergo reactions to form new substances.
Chemical Change
A reaction between two substances or the decomposition of a substance are chemical changes.
The initial substances in a chemical reaction are called reactants.
The substances that are changed in a chemical reaction are known as reactants. These reactants undergo a chemical change or transformation to form new substances called products through the rearrangement of their atoms.
A change from one or more substances to another is a chemical change.
