has a definite shape and a definite volume
particles that form a regular, repeating pattern
solids that are made up of crystals and melt at a specific temperature
particles that are not arranged in a regular pattern and does not melt at a distinct temperature
has a definite volume but no shape of its own
a substance that flows
the result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together
a liquid's resistance to flowing
changes volume very easily
the change in state from a solid to a liquid
the specific temperature at which melting occurs
the change of state from a liquid to a solid
the change from a liquid to a gas
vaporization that takes place only on the surface of a liquid
when a liquid changes to a gas below its surface as well as at the surface
the temperature at which a liquid boils
the opposite of vaporization; when particles in a gas lose enough thermal energy to form a liquid
when the surface particles of a solid gain enough energy that they form a gas. They do not pass through the liquid state as they form a gas
the force of its outward push divided by the area of the walls of the container.
when the pressure of a gas at a constant temperature is increased, the volume of the gas decreases. When the pressure is decreased, the volume increases
when the temperature of a gas is increased at constant pressure, its volume increases. When the temperature of a gas is descreased at a constant pressure, its volume decreases
a diagram that tells how two variables, or factors that change, are related.
the point (0,0)
when a graph of two variables is a straight line passing through the origin
when a graph of two variables forms a curve that shows the relationship between pressure and voume known as Boyle's law
