Properties Of Matter

Front 1

Chemical Property

Back 1

a property or characteristic of a substance that is observed during a reaction in which the chemical composition or identity of the substance is changed

Front 2

Density

Back 2

the state or quality of being dense; compactness; closely set or crowded condition.

Front 3

Flammability

Back 3

How easily something is set on fire

Front 4

mass

Back 4

a body of coherent matter, usually of indefinite shape and often of considerable size

Front 5

matter

Back 5

the substance or substances of which any physical object consists or is composed

Front 6

volume

Back 6

the amount of space that a substance or object occupies, or that is enclosed within a container, especially when great.

Front 7

reactivity

Back 7

the state or power of being reactive or the degree to which a thing is reactive.

Front 8

weight

Back 8

a body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing.

Front 9

atom

Back 9

the basic unit of a chemical element.

Front 10

colloid

Back 10

a homogeneous, noncrystalline substance consisting of large molecules or ultramicroscopic particles of one substance dispersed through a second substance. Colloids include gels, sols, and emulsions; the particles do not settle and cannot be separated out by ordinary filtering or centrifuging like those in a suspension.

Front 11

compound

Back 11

a thing that is composed of two or more separate elements; a mixture.

Front 12

element

Back 12

a part or aspect of something abstract, especially one that is essential or characteristic.

Front 13

mixture

Back 13

a substance made by mixing other substances together.

Front 14

molecule

Back 14

a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.

Front 15

solution

Back 15

a means of solving a problem or dealing with a difficult situation.

Front 16

suspension

Back 16

the action of suspending someone or something or the condition of being suspended, in particular.

Front 17

law of conservation of mass

Front 18

physical change

Front 19

Engery

Back 19

the strength and vitality required for sustained physical or mental activity.

Front 20

Neutron

Back 20

a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.

Front 21

freezing

Back 21

below 32°F (0°C)

Front 22

Melting

Back 22

make or become liquefied by heat.

Front 23

Sublimination

Back 23

When anything solid turns into a gas without first becoming liquid, that's sublimation.

Front 24

chemical change

Back 24

Chemical change is any change that results in the formation of new chemical substances.
