solid

state of matter whose particles are tightly packed and vibrating in place.

liquid

state of matter whose particles can easily slide past one another

gas

state of matter whose particles are moving very fast, continuously bouncing off one another

evaporation

an endothermic change that results in a liquid changing into a gas

condensation

an exothermic change that results in a gas changing into a liquid

melting

an endothermic change that results in a solid changing into a liquid

freezing

an exothermic change that results in a liquid changing into a solid

sublimation

an endothermic change that results in a solid changing directly into a gas

deposition

an exothermic change that results in a gas changing directly into a solid

Boyle's Law

When temperature is constant, volume and pressure are indirectly proportional.

Charles's Law

When the pressure is constant, temperature and volume are directly proportional.

pressure

caused by the collisions of gas particles with the sides of the container

volume

the amount of space matter take up

thermal energy

heat

kinetic energy

energy of motion

endothermic change

change that is a result of thermal energy (heat) being added

exothermic change

change that is a result of thermal energy (heat) being removed

plasma

state of matter with the weakest intermolecular attraction and most kinetic energy among its particles

Bose-Einstein Condensate

state of matter with the strongest intermolecular attraction and the least amount of kinetic energy

Temperature

A measure of the average energy of motion of the particles of a substance.
