A pure substance made of only one type of atom.

A substance formed from two or more elements chemically combined.

A characteristic of matter that can be observed or measured without changing its chemical composition.

A change in the appearance or physical properties of a substance without changing its chemical composition.

A property of matter that depends on the amount of matter present.

A property of matter that does not depend on the amount of matter present.

The ability of a substance to undergo a chemical change or reaction.

A change in the physical state of a substance (solid, liquid, gas) caused by absorbing or releasing heat.

A compound is formed when two or more elements chemically combine.

Physical properties can be observed without changing the substance's chemical makeup. Chemical properties describe how a substance reacts or changes into a new substance.

Extensive properties depend on the amount of matter present, like volume or mass.

The ability of a substance, usually a liquid or gas, to catch fire easily.

The tendency of a liquid to vaporize or evaporate.

Rusting is a chemical reaction between a metal and moisture in the air, creating iron oxide.

Solids have a definite shape and volume. Liquids have a fixed volume but take the shape of their container. Gases have no fixed shape or volume.

Plasma forms when gas particles gain energy (heat or electricity) and become ionized.

A state of matter where atoms are supercooled to near absolute zero and act like a single entity.

A reversible physical change that alters a substance's state of matter by absorbing or releasing heat.
