|
solid
|
a state of matter that has a definite shape and volume
|
|
|
crystalline solid
|
a solid that is made up of crystals in which particles are arranged in a regular, repeating pattern
|
|
|
amorphous solid
|
a solid made up of particles that are not arranged in a regular pattern
|
|
|
liquid
|
a state of matter that has no definite shape but has a definite volume
|
|
|
fluid
|
any substance that can flow
|
|
|
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
|
|
|
viscosity
|
a liquid's resistance to flowing
|
|
|
gas
|
a state of matter with no definite shape or volume
|
|
|
melting
|
the change in the state from a solid to a liquid
|
|
|
melting point
|
the temperature at which a substance changes from a solid to a liquid
|
|
|
freezing
|
the change in state from liquid to solid
|
|
|
vaporization
|
the change in state from liquid to a gas
|
|
|
evaporization
|
the process that occurs when vaporization takes place only on the surface of a liquid
|
|
|
boiling
|
the process that occurs when vaporization takes place inside a liquid as well as on the surface
|
|
|
boiling point
|
the temperature at which a substance changes from a liquid to a gas
|
|
|
condensation
|
the change of state from a gas to a liquid
|
|
|
sublimation

a principle that describes the relationship between the pressure and volume of a gas at constant temperature
|
|
|
Charles's law
|
a principle that describes the relationship between the temperature and volume of a gas at constant pressure
|
|
|
graph
|
a diagram that shows how two variable are related
|
|
|
origin
|
the (0,0) point on a line graph
|
|
|
directly proportional
|
a term used to describe the relationship between two variables whose graph is a straight line passing through the point (0,0)
|
|
|
vary inversely
|
a term used to describe the relationship between two variables whose graph forms a curve that slopes downward
|
|
