Solid
the state of matter in which a material has a definite volume but not a definite shape.
Liquid
the state of matter in which a material has neither a definite shape nor a definite volume.
Gas
the energy an object has due to its motion.
Kinetic energy

Absolut zero
Direct proportion- Volume + Temperature
Charles law
inverse proportion. volume + pressure
Boyle's law
a reversible physical change that occurs when a substance changes from one state of matter to another.
Phase change
description of a change in which a system absorbs energy from its surroundings.
endothermic
the energy a substance must absorb in order to change from a solid to a liquid.
Heat of fusion
a description of a change in which a system releases energy to its surroundings.
endothermic
the phase change in which a substance changes from a liquid into a gas.
Vaporization
the energy a substance must absorb in order to change from a liquid to a gas.
Heat of vaporization
the process that changes the substance from a liquid to a gas at temperatures below the substance's boiling point.
Evaporation
the pressure caused by the collisions of particles in vapor with the walls of a container.
