Chemical vs. Physical

Chemical Properties are properties that are observed when matter is rearranged.

The chemical properties of matter are:

- flammability
- ability to react (reactivity)


Physical Properties are properties that can be observed without changing the object/substance. (ex. this orange has a very bumpy texture)

The physical properties of matter are:
- physical state
- texture
- color
-flexibility



Chemical Change is a change in matter that produces one or more new substances.

Examples:

- Combustion: rapid combination of a fuel with oxygen; produces heat, light, and new substances.
- Electrolysis: use of electricity to break a compound into elements or simpler compounds.
- Oxidation: slow combination of a substance with oxygen
- Tarnishing: slow combination of a bright metal with sulfur or another substance producing a dark coating on the metal.
