	Term	Definition
	Solid	Definite shape and volume
	Liquids	Definite volume but no definite shape
	Gas	No definite shape or volume
	Plasma	99% of all the matter that exists on the earth
	Kinetic Energy	the energy an object has due to motion
	Motion in gases	there are forces of attraction among the particles in all matter
	Pressure	the result of a force distributed over an area. Measured in Newtons
	Temperature	raising it of a gas will increase its pressure if the volume of the gas and the number of particles are constant
	Volume	reducing the volume of a gas increases its pressure if the temperature of the gas and the number of particles are constant
	Number of Particles	increasing the number of particles will increase the pressure of a gas if the temperature and the volume are constant
	Charles's Law	states that the volume of a gas is directly proportional to its temp. in kelvins if the pressure and the number of particles of the gas are constant
	Boyle's Law	states that the volume of a gas in inversely proportional to its pressure if the temp. and the number of particles are constant
	Phase Change	solid to liquid to gas and back
	Vaporization	liquid to gas change
	Evaporation	the change from a liquid to a gas
	Condensation	The act or process of making dense or denser.
	Sublimation	solid changes to gas (it doesn't go to liquid first)
	Deposition	exothermic, gas to solid
