Liquid

Definite volume but no definite shape.

Gas

No definite volume or shape.

Gas Volume and Temperature

Volume increases as temperature rises.

Solubility

Physical property describing a substance's ability to dissolve.

Water State Change

Liquid water boils to form water vapor.

Physical Change

Alters form or shape without changing chemical makeup.

Non-State Physical Change

Crushing or breaking an object with a hammer.

Chemical Change

Forms entirely new and different substances.

Compound

Substance made of two or more chemically combined atom types.

Conservation of Mass

Mass remains completely identical during state changes.

Closed System Mass

Total mass stays exactly the same during gas-producing reactions.

Solution

Uniform mixture with the same composition throughout.

Oil and Water Separation

Letting oil float to the top to skim it off.

Steel Alloy Properties

Formulated to be strong and slightly flexible.

Dissolving Rate Factors

Affected by temperature, particle size, and stirring speed.

Irrelevant Dissolving Factor

Solid color has zero impact on dissolving rate.
