Term
What are the similarities and differences between solid, liquid, and gases?
Definition
Solids have a definite shape and volume. Gases have no definite shape & volume.Liquids have a definite volume.
Term
solid
Definition
has a definite shape and definite volume
Term
liquid
Definition
definite volume but no shape of its own
Term
gas
Definition
does not have a definite shape or a definite volume
Term
viscosity
Definition
A liquids resistance to flow
Term
vibrate
Definition
move back and forth slightly
Term
crystalline solids
Definition
solids that are made up of crystals such as salt, snow, and sugar. Melts in distinct temperatures.
Term
amorphous solid
Definition
particles are not arranged in a regular pattern. Does not melt at a distinct temperature. such as rubber or plastic
Term
temperature
Definition
The measure of the average kinetic energy of the particles in an object
Term
Freezing
Definition
the change of state from liquid to a solid
Term
evaporation
Definition
vaporization that occurs about the surface only
Term
vaporization
Definition
the change in state of liquid to a gas
Term
sublimation
Definition
the change in state from solid to a gas
Term
boiling
Definition
vaporization that take place both above and below the surface
Term
condensation
Definition
the change in state from gas to a liquid
Term
Melting
Definition
the change of state from solid to liquid
Term
thermal energy
Definition
the total kinetic and potential energy of all the particles in an object
Term
Amorphous and crystalline are two examples of
Definition
solids
Term
What causes matter to change from one state to another?
Definition
Adding or removing energy from matter causes a physical change as matter moves from one state to another. For example, adding thermal energy (heat) to liquid water causes it to become steam or vapor (a gas).
Term
what two properties of gas depend on its container?
Definition
Shape and volume
Term
How do liquids with high viscosity differ from liquids with low viscosity?
Definition
Liquids with high viscosity flow more slowly than those with low viscosity.
