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.
