Mass

A measure of the amount of matter that an object contains; the SI base unit of mass is the kilogram.

Volume

A measure of the space occupied by a sample of matter.

Extensive Property

A property that depends on the amount of matter in a sample.

Intensive Property

A property that depends on the type of matter in a sample, not the amount of matter.

Substance

Matter that has a uniform and definite composition, either an element or a compound; also called pure substance.

Physical Property

A quality or condition of a substance that can be observed or measured that flows, has a fixed volume, and an indefinite shape.

Solid

A form of matter that has a definite shape and volume.

Liquid

A form of matter that flows, has a fixed volume, and an indefinite shape.

Gas

A form of matter that takes the shape and volume of its container; a gas has no definite shape or volume.

Vapor

Describes the gaseous state of a substance that is generally a liquid or solid at room temperature.

Physical Change

A change during which some properties of a material change, but the composition of the material does not change.

Mixture

A physical blend of two or more substances that are not chemically combined.

Heterogeneous Mixture

A mixture that is not uniform in composition, components are not evenly distributed throughout the mixture.

Homogeneous Mixture

A mixture that is uniform in composition, components are evenly distributed and not easily distinguished.

Solution

A homogeneous mixture; consists of solutes dissolved in a solvent.

Phase

Any part of a sample with uniform composition and properties.

Filtration

A process that separates a solid from the liquid in a heterogeneous mixture.

Distillation

A process used to separate dissolved solids from a liquid, which is boiled to produce a vapor that is then condensed into a liquid.

Element

That simplest form of matter that has a unique set of properties; an element cannot be broken down into simpler substances by chemical means.

Compound

A substance that contains two or more elements chemically combined in a fixed proportion.

Chemical Change

A change that produces matter with a different composition than the original matter.

Chemical Symbol

A one- or two- letter representation of an element.

Chemical Property

The ability of a substance to undergo a specific chemical change.

Chemical reaction

A change in which one or more reactants change into one or more products, characterized by the breaking of bonds in reactants and the formation of bonds in products.

Reactant

A substance present at the start of the reaction.

Product

A substance produced by the reaction.

Precipitate

A solid that forms and settles out of a liquid mixture.

Law of conversation of mass

In any physical change or chemical reaction, mass is conversed, mass can be neither created nor destroyed.

Reversible/Irreversible

Physical Changes can be classified as:

Solid/Liquid/Gas

Three states of matter:

Heterogeneous/Homogeneous

Two types of mixtures:

Compounds

What can be broken down into simpler substances?

Substance

If the composition of a material is fixed, the material is a:

Chemical Symbols

What do Chemists use to represent elements?

Chemical Formulas
