High School General Chemistry Review: Properties of Matter

This set of flashcards covers essential vocabulary and concepts related to the properties of matter, including definitions and descriptions of physical and chemical changes, types of mixtures, and various scientific techniques.

Chemical Change

A process in which bonds are broken and rearranged to form a new substance.

Physical Change

A change where the chemical composition stays the same, but the spacing between the molecules changes.

Homogeneous Mixture

A mixture with a uniform composition throughout.

Heterogeneous Mixture

A mixture where components are visibly distinct.

Endothermic Change

A change that absorbs energy (heat) from the surroundings.

Exothermic Change

A change that releases energy (heat) to the surroundings.

Law of Conservation of Mass

States that no matter is created nor destroyed in a chemical reaction; the mass of reactants equals the mass of products.

Sublimation

The process of a substance changing directly from a solid to a gas.

Density

An intensive property that does not depend on the amount of matter.

Extensive Property

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

Filtration

A technique used to separate a heterogeneous mixture by pouring it through filter paper.

Distillation

A technique used for separating a soluble salt from water.

Evaporation

The process where a liquid turns into gas at its surface.

Condensation

The process where a gas turns into a liquid.
