Category 1
The amount of matter in an object
the positively charged parts of atoms
protons
the particle speed is slower than in a gas and faster in a solid
Liquid
temperature at which matter changes from liquid to solid
freezing point
solid becomes gas without being a liquid
deposition
the amount of space that a sample of matter occupies
Volume
negatively charged part of atoms
electrons
the particle speed is fastest and the attractive force between particles is the weakest
Gas
stored energy resulting from the interactions between particles or objects
potential energy
measure of the average kinetic energy of all the particles in an object
temperature
mass per unit volume
density
the particle speed is slowest and the attractive force between particles is strongest
Solid
the temperature at which a solid state changes to a liquid state.
melting point
vaporization that occurs only at the surface of a liquid
evaporation
change in state from a liquid to a gas.
ways in which atoms, ions, or molecules move
particle motion
oppositely charged particles attract each other
particle force
can result from adding or removing thermal energy.
change of state
energy an object has due to its motion
kinetic energy
states that as the volume of a gas changes, so does its pressure and the temperature is a constant.
Boyle's Law
high energy matter consisting of positively and negatively charged particles
Plasma
movement in all directions and at different speeds
random motion
the change of state from a gas to a liquid
condensation
gas becomes solid without being a liquid
sublimation
states that as the temperature of a gas changes, so does its volume and the pressure is a constant.
Charles' Law
