Melting-
The change in state from a solid to a liquid is called melting.
Melting point-
In most pure substances, melting occurs at a specific temperature, called the melting point.
Freezing-
The change of state from liquid to solid is called freezing.
Vaporization-
The change from a liquid to a gas is called vaporization.
Evaporation-
Vaporization that takes place only on the surface of a liquid is called evaporation.
Boiling-
Another kind of vaporization is called boiling. Boiling occurs when a liquid changes to a gas below its surface as well as at the surface.
Boiling point-
The temperature at which a liquid boils is called its boiling point.
Condensation-
The opposite of vaporization is called condensation.
Sublimation-
Sublimation occurs when the surface particles of a solid gain enough energy that they form a gas. During sublimation, particles of a solid do not pass through the liquid state as they form a gas.
Pressure-
the outward push of the gas divided by the area of the walls.
Boyle's Law-
states that if you increase the volume then the pressure decreases.
Charles's law-
States that if you increase the temperature then the pressure increases.
Graph -
A diagram that tells you how two variables, or factors that change, are related
Origin -
A line that passes through the point (0,0)
Directly Proportional -
When the graph of two variables is a straight line passing through the origin
Vary Inversely -
When a graph of two variables forms curve
Solid
Has a definite shape and a definite volume
Crystalline Solids
Solids that are made up of crystals
Amorphous Solids
The particles are not arranged in a regular pattern
Liquid
Has a definite volume but no shape of its own
Fluid
is a liquid; "a substance that flows
Surface Tension
Is the result of an inward pull among molecules of a liquid that brings the molecules on the surface closer together
Viscosity
A liquid's resistance to flowing
Gas
Has no definite volume or shape
