Solid

A state of matter that has a definite shape and a definite volume.

1

Crystalline Solid

A solid that is made up of crystals in which particles are arranged in a regular, repeating pattern.

2

Amorphous Solids

A solid made up of particles that are not arranged in a regular pattern.

3

Liquid

A state of matter that has no definite shape but has a definite volume.

4

Liquid

Any substance that can flow

5

Surface Tension

The result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together; causes the surface to act as if it has a thin skin

6

Viscosity

A liquid’s resistance to flowing.

7

Gas

A state of matter with no definite shape or volume

8

Pressure

The force pushing on a surface divided by the area of that surface.

9

Melting

The change in state from a solid to a liquid

10

Melting Point

The temperature at which a substance changes from a solid to a liquid; the same as the freezing point, or temperature at which a liquid changes to a solid.

11

Freezing

The change in state from a liquid to a solid.

12

Vaporization

The change of state from a liquid to a gas.

13

Evaporation

The process by which molecules at the surface of a liquid absorb enough energy to change to a gas.

14

Boiling

Vaporization that occurs at and below the surface of a liquid.

15

Boiling Point

The temperature at which a liquid boils

16

Condensation

The change in state from a gas to a liquid.

17

Sublimation

The change in state from a solid directly to a gas without passing through the liquid state.

18

Charles's Law

A principle that describes the relationship between the temperature and volume of a gas at constant pressure

19

Directly Proportional

A term used to describe the relationship between two variables whose graph is a straight line passing through the point (0, 0).

20

Boyle's Law

A principle that describes the relationship between the pressure and volume of a gas at constant temperature.

21

Inversely Proportional

A term used to describe the relationship between two variables whose product is constant
