Chemistry Unit 1: Properties Of Matter

Front 1

Pure substance:

Back 1

Matter that always has exactly the pure substance, or simply a substance.

Front 2

Element:

Back 2

Is a substance that can't be broken down into simpler substance.

Front 3

Atom:

Back 3

Is the smallest particle of an element.

Front 4

Compound:

Back 4

Is a substance that is a substance that is made from two or more substance and can be broken into those similer substances.

Front 5

Heterogeneuous mixture:

Back 5

Is the parts of the mixture are noticeably different from one another.

Front 6

Homogeneous mixture:

Back 6

The substance are evenly disturbed that it is difficult to distinguish one substance in the mixture from another.

Front 7

Solution: (page 42)

Back 7

When substance dissolve and form a homogeneous mixture.

Front 8

Suspension: (page 43)

Back 8

Is a heterogenous mixture that seperates into layers over time.

Front 9

Colloid: (page 44)

Back 9

Contains some particles that are intermediate in size bewteen the small particles in a solution and the larger particles in a supsension.

Front 10

Physical Science: (page 45)

Back 10

Is any characteristic of a material that can be observed or measured without changing the composition of the substances in the material.

Front 11

Viscosity: (page 45)

Back 11

The tendency of a liquid to keep from flowing its resistance to flow.

Front 12

Conductivity: (page 46)

Back 12

Is the ability of a material to allow heat to flow.

Front 13

Malleability: (page 46)

Back 13

Is the ability of a solid to be hammered without shattering.

Front 14

Melting point: (page 47)

Back 14

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

Front 15

Boliling point: (page 47)

Back 15

Is the temperature at which a substance boils.

Front 16

Hardness. (page 47)

Back 16

Is the ability of a material to be scratched, cut, or carved by ( or do the same to) another material.

Front 17

Density: (page 47)

Back 17

Is the ratio of the mass of a substance to it's volume.

Front 18

Physical Change: (page 51)

Back 18

Occurs when some of the properties of a material change, but the substance in the material remain the same.

Front 19

Chemical Change: (page 54)

Back 19

Is any ability to produce a change in the composition of matter.

Front 20

Flammability: (page 54)

Back 20

Is a material ability to burn in the presence of oxygen.
