Matter Flashcards

Matter

The amount of space something takes up in a given volume

Chemistry

Chemistry is the scientific study of matter—its composition, structure, properties, and the changes it undergoes during chemical reactions.

Solid

Has definite shape and volume. Has particles that are packed closely together and usually arranged in a regular pattern

Liquid

Has a definite volume but no fixed shape. Has particles that can move and are in close contact.

Gas

Has no definite volume and shape. Has particles that are wildly spread

Plasma

Has no definite volume and shape. Has charged particles that are wildly separated

Pure Substance

A single kind of matter that has a specific make up and has a specific set of properties. Ex:Table salt

Physical Property

Can be observed without changing the identity of the substance. Ex: Color, shape, hardness, texture, mass, weight, volume

Chemical Property

When you change a chemical form into a completely different one

Atoms

Building blocks for matter

Element

A substance that can not be broken into any simpler substance

Compound

A substance made up of 2 or more elements chemically combined in exact ratio 

Mixture

two or more substances combined but not chemically

Homogeneous

Appears to be the same Ex: Soda

Heterogeneous

least mixed - materials large enough to be seen Ex: Soil, muddy water

Colloid

Homogeneous mixture in which particles are mixed but not dissolved
