Solid
|
has a definite volume and a definite shape
|
|
|
Crystalline Solid
|
Solids that are made up of crystals and have a specific melting point
|
|
|
melting point
|
The distinct temperature at which a solid melts
|
|
|
amorphous solid
|
the particles are not arranged in regular patterns and they do not have a specific melting point
|
|
|
liquid
|
has an indefinite shape but a definite volume
|
|
|
viscosity
|
resistance of a liquid to flow
|
|
|
gas
|
has an indefinite shape and an indefinite volume
|
|
|
temperature
|
the measure of the average energy of motion of the particles of a substance
|
|
|
pressure
|
is the force of its outward push divided by the area of the walls of the container
|
|
|
Boyle's Law
|
The relationship between the pressure and volume of a gas
|
|
|
Charles's Law
|
the relationship between the temperature and volume of gas
|
|
|
graph
|
a diagram that tells how two variables are related
|
|
|
directly proportional
|
When a graph of two variables is a straight line passing through the (0,0) point. The relationship is linear.
|
|
|
vary inversely
|
When a graph of two measurements forms a curve. The relationship is nonlinear.
|
|
|
thermal energy
|
the energy that the particles of a substance have
|
|
|
melting
|
change in state from a solid to a liquid
|
|
|
freezing
|
change in state from a liquid to a solid
|
|
|
vaporization
|
general change in state from a liquid to a gas
|
|
|
evaporation
|
vaporization that takes place only on the surface of a liquid
|
|
|
boiling
|
vaporization that takes place inside a liquid as well as on the surface
|
|
|
boiling point
|
the specific temperature at which a liquid boils
|
|
|
Condensation
|
Occurs when gas particles lose enough thermal energy to become a liquid
|
|
|
sublimation
|
Occurs when the surface particles of a solid gain enough energy to become a gas.
