Term
solid
Definition
has a definite shape and a definite volume
Term
crystalline solids
Definition
solids that are made of crystals
Term
amorphous solids
Definition
when the particles in a solid are not arranged in a regular pattern
Term
liquid
Definition
has a definite volume but indefinite shape
Term
fluid
Definition
substance that flows
Term
surface tension
Definition
an inward force, or pull, among the molecules of a liquid that brings the molecules on the surface closer together
Term
viscosity
Definition
a liquid's resistance to flowing
Term
gas
Definition
has an indefinite shape and volume
Term
pressure (of a gas)
Definition
the force of a gas's outward push divided by the area of the walls of the container
Term
melting
Definition
change in state from solid to liquid
Term
melting point
Definition
the point at which a solid melts
Term
freezing
Definition
change in state from liquid to solid
Term
vaporization
Definition
change in state from liquid to gas
Term
evaporation
Definition
vaporization that takes place at the surface of a liquid
Term
boiling
Definition
vaporization that takes place both below and at the surface of a liquid
Term
boiling point
Definition
the temperature at which a liquid boils
Term
condensation
Definition
the change in state from a gas to a liquid
Term
sublimation
Definition
the change of state from a solid directly to a gas
Term
Charles's Law
Definition
states that when the temperature of a gas at a constant pressure is increased, its volume increases. When temperature decreases, volume decreases.
Term
directly proportional
Definition
a term used to describe the relationship between two variables whose graph is a straight line passing through point (0,0)
Term
Boyle's Law
Definition
states that when the pressure of a gas at constant temperature is increased, the volume of the gas decreases. When the pressure is decreased, volume increases
Term
inversely proportional
Definition
when the product of two variables is constant
