Matter Matter is composed of tiny particles that are always in constant motion

Kinetic Theory of Matter
Describes how the individual particles in
matter move

Solids Solids have very little particle movement
(simple vibration back and forth).
Can NOT flow
Solids are also hard to compress.

Liquids
Liquids have moderate particle motion.
The particles of a liquid can easily slide past one another (FLOW)
Liquids are hard to compress because their particles are close together.

Gases Gases particles are in constant, fast,
random motion.
Gas particles are very far away from each other.
Gases can be compressed.

Physical vs. Chemical Change
Physical change will change the visible appearance, without changing the composition of the material. – Boil, melt, cut, bend, split, crack
– Can be reversible, or irreversible
– All changes in state of matter are physical changes

Physical vs. Chemical Change
Chemical change - a change where a new form of matter is formed. – Also called a chemical reaction
– Terms that indicate chemical change include: »Rust, burn, decompose, ferment,
explode, oxidize, corrode, tarnish, rot

Chemical Change A change in which one or more substances are converted into different substances.
Heat and light are often evidence of a chemical change.
