Term Definition
thermal energy total kinetic energy of the particles of a substance
heat thermal energy that flows from higher temp. to a lower temp.
energy the ability to cause work and change
matter anything that has mass and takes up space
density physical property of matter that can be found by dividing the matter's mass by it's volume
state of matter physical property that describes a substance as a solid, liquid or gas
evaporation to turn fom a solid or a liquid into a gas
vaporization change from a liquid state to a gas
condensation change of matter from a gas to a liquid state
melting point temp. at which any given solid will melt
boiling point temp. at which liquid starts to boil
pressure amount of force applied per unit on an objects surface
boyant force upward force exherted on an objectimmersed in a fluid
Archimedes' Principle states the boyant force on an object is equal to the weight of the fluid displaced by the object
Pascals principle the term refering to the pressure applied at any point to a confined fluid being transmitted unchanged throughout the fluid
gas matter that does not have a definite shape or volume particales are far apart and movement at high speeds completly fills it's container, particals have enoughenergy to pull apart from their attraction
solid definent shape and volume, particles are packed tight- vibrating in place does not take the shape of its container particles do not have enough energy to pull appart from their attraction
liquid matter that has a definite volume but not a definite shape particles are moving freely but do not have enough energy to pull apart from ea. other takes the shape takes the shape of it's container
kinetic energy energy of motion
amorphous solids solids with a random arrangment of particles

rake23 : Changed thermal heat → total kinetic energy of the particles of a substance to thermal energy → total kinetic energy of the particles of a substance
rake23 : Changed amorphous solid → solids with a random arrangment of particles to amorphous solids → solids with a random arrangment of particles
rake23 : Changed Archimedes' Princeple → states the boyant force on an object is equal to the weight of the fluid displaced by the object to Archimedes' Principle → states the boyant force on an object is equal to the weight of the fluid displaced by the object
