states of matter

solid, liguid, gas and plasma

kinetic theory of matter

tiny particles in constant motion make up all matter


particles arranged in repeating geometric patterns


a gaslike mixture

thermal expansion

almost all matter expands when it gets hot and contracts when it cools

polluted water

water that contains high levels of unwanted materials

thermal pollution

excess heat in water


liquid changes to gas


gas changes to liquid

heat of fusion

amount of heat needed to change material from a solid to a liquid

heat of vaporization

amount of heat needed to change material from a liquid to a gas


amount of force excerted per unit area (P=F/A)


Pa is the SI unit of pressure

Boyle's Law

If you decrease volume of gas, the pressure will increase provided there is no temperature change

Charles's Law

The volume of gas increases with increasing temperature provided that the pressure does not change

bouyant force

ability of water to exert an upward force on an object

Archimedes' principle

the bouyant force on an object equals the weight of fluid being displaced by the object

Pascal's principle

pressure applied to a fluid is transmitted evenly throughout

Bernoulli's principle

as velocity of a fluid increases, the pressure decreases

Venturi Effect

fluids will flow faster through narrow spaces
