Term Definition
Solid A state of matter in which materials have a definite shape and definite volume
Liquid A state of matter in which a material has a definite volume but not a definite shape
Gases A state of matter in which a material does not have a definite shape or volume
Kinetic Energy Energy of an object due to a motion.
Kinetic Theory The constant motion of particles in a gas allows a gas to fill a container of any shape or size
Pressure The result of a force distributed over an area
Absolute Zero A temperature of 0 K
Charles's Law The volume of a gas is directly proportional to its temperature in kelvins if the pressure and the number of particles of the gas are constant
Boyle's Law The volume of a gas in inversely proportional to its pressure if the temperature and the number of particls are constant
Combined Gas Law The relationship among the temperature, volume, and pressure of a gas when the number of particles are constant
Phase Change The reversible physical change that occurs when a substance changes from one state of matter to antoher
Endothermic Change The system absorbs energy from its surroundings
Fusion Melting
Evaporation Liquid to gas at temperatures below the substances boiling point
Exothermic Change The system releases engery to its surroundings
Vaporization Liquid to gas
Condensation The phase change in which a substance changes froma gas or vapor to a liquid
Sublimation The phase change in which a substance changes from a solid to a gas or vapor
Deposition When gas or vapor changes directly into a solid without first changing into a liquid
