|
Archimedes' principle
|
the greek mathematician Archimedes stated that the buoyant force on an object is a fluid is equal to the weight of the fluid displaced bye the object.
|
|
|
bermoulli's principle
|
the swiss scientist daniel bernoulli stated that as the velocity of a fluid increases, the pressure exerted by the fluid decreases.
|
|
|
boyle's law
|
british scientist robert boyle stated that the volume of a gas decreases when the pressure increases, provided the temperature stays the same.
|
|
|
buoyant force
|
ability of a fluid to exert an upward force on an object inersed in the fluid.
|
|
|
charle's law
|
french scientist jacques charles stated that the volume of a gas increases when the temperature increases, provided the pressure stays the same.
|
|
|
condensation
|
the change of a substance from a gas to a liquid, which usually takes place when a gas is cooled to or below its boiling point.
|
|
|
crystal
|
in most solids, the arangements of particles in repeating geometric patterns

|
|
evaporation
|
the gradual change of a substance from a liquid to a gas at temperature below the boiling point.
|
|
|
heat of fusion
|
the amount of energy needed to change a material from the solid state to the liquid state.
|
|
|
heat of vaporization
|
the amount of evergy needed to change a liquid to a gas.
|
|
|
kinetic theory of matter
|
the idea that all matter is made up of constantly moving, tiny particles.
|
|
|
pascal
|
the SI unit of pressure.
|
|
|
pascal's principle
|
french scientist blaise pascal stated that pressure applied to a fluid is transmitted unchanged through the liquid.
|
|
|
plasma
|
a gaslike mixture of charged and negatively charged particles that exists at extremly high temperatures.
|
|
|
polluted water
|
water that contains high levels of unwanted substances that may be harmful to living things.
|
|
|
pressure
|
the amount ot force exited per unit of area.
|
|
|
states of matter
|
any of the four conditions in which matter can exist
|
|
|
thermal expanstion
|
a characteristic of all matter that causes it to expand when heated, and contract when cooled.
|
|
|
thermal pollution
|
pouution caused when wasts heat rises the temperature of the environment
|
|
|
ventri effect
|
reduction in pressure of a fluid resulting from the speed increase as fluids are forced to flow faster through narrow spaces.
