TermDefinition
A state of matter that has a definite shape and definite volume. solid
A solid that is made up of crystals in which particles are arranged in a regular, repeating pattern, and which have a definite MP/FP. crystalline solid
A solid made up of particles that are not arranged in a regular pattern, and has no definite MP/FP. amorphous solid
A state of matter that has no definite shape, but does have a definite volume. liquid
Any substance that can flow such as a liquid or a gas. fluid
The resistance of a liquid to flowing. viscosity
A state of matter with no definite shape or volume. gas
The measure of the average energy (kinetic) of the particles of a substance. temperature
A force pushing on a surface divided by the area of that surface. pressure
The relationship between the volume and the pressure of a gas; when volume increases, pressure decreases. (BVP) Boyle's Law
The relationship between the temperature and the volume of a gas; when temperature increases, volume increases. (CTV) Charles's Law
A diagram that shows how two variables are related. graph

The process that occurs when vaporization takes place only on the surface of a liquid. evaporation
The process that occurs when vaporization takes place inside a liquid as well as on the surface of the liquid. boiling
The change of state from a gas to a liquid. condensation
