Electrical Conductivity

is a measure of how easily electricity can pass through a substance.

Home

Magnetism

is a measure of how attracted a substance is to a magnet

Home

Meniscus

The upward curve at the surface of a liquid

Home

Atom

The basic particle from which all elements are made; the smallest particle of an element that has the properties of that element

Home

Density

is a measure of how easily electricity can pass through a substance.

Home

Physical Property

is a characteristic of a substance that can be observed or measured without changing the identity of the substance.

Home

Boiling Point

is the temperature at which a substance changes from liquid to gas

Home

Element

A substance that contains one kind of atom and cannot be broken down into a simpler form

Home

Home

Pure Substance

consists of just one type of particle and has the same physical properties throughout Ex) Elements and Compounds

Home

Heterogeneous Mixture

A mixture that is not the same throughout.

Home

Displacement

A way to measure the volume of a solid by placing it in a known amount of liquid

Home

Color

is determined by what colors of light are reflected by a substance. If light just passes through the substance, the substance may lack color.

Home

Homogeneous Mixture

A mixture that is the same throughout.

Home

Fluid

A substance that has no fixed shape and is able to flow easily; a gas or a liquid

Home

Compound

A substance made of two or more elements chemically combined in a specific ratio or proportion

Home

Mixture

is made of two or more substances that are combined but whose atoms are not chemically bonded. The substances that make up the mixture keep their own physical properties

Home

Mass

Amount of matter a body contains

Home

Melting Point

is the temperature at which a substance changes from solid to liquid.

Home

Freezing Point

the temperature at which a liquid turns into a solid when cooled.

Home

Volume

the amount of space that a substance or object occupies

Home

Chemical Formula

A shorthand notation that uses chemical symbols and numbers as subscripts to represent the type of atoms and number of atoms that are present in the smallest unit of the substance.
