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
almost all matter expands when it gets hot and contracts when it cools
water that contains high levels of unwanted materials
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
If you decrease volume of gas, the pressure will increase provided there is no temperature change
The volume of gas increases with increasing temperature provided that the pressure does not change
ability of water to exert an upward force on an object
the bouyant force on an object equals the weight of fluid being displaced by the object
pressure applied to a fluid is transmitted evenly throughout
as velocity of a fluid increases, the pressure decreases
fluids will flow faster through narrow spaces
