Question | Answer |
---|---|
shape of solid | definite |
volume of solid | definite |
arrangement of solid | tightly packed |
motion of solid | vibrate in place |
shape of gas | non definite |
volume of gas | non definite |
arrangement of gas | spread apart |
motion of gas | move freely |
shape of liquid | non definite |
volume of liquid | definite |
arrangement of liquid | close enough to pass each other |
motion of liquid | able to slide past |
melting | solid to liquid |
vaporization | liquid to gas |
sublimation | solid to gas |
freezing | liquid to solid |
condensation | gas to liquid |
crystalline solid | regular repeating pattern , form crystals |
amorphous solid | no pattern, shape-less |
Boyles Law | pressure and volume. inverse relationship. volume of a gas increases the pressure decreases (vice versa) |
Charles Law | volume and temperature. direct proportion. one factor increases so does the other (vice versa) |
Archimedes Principle | buoyancy and density. the buoyant force is equal to the weight of the fluid disguised by the object. |
Pascals Principle | force and pressure. if a force exerted in a confined fluid it is transmitted uncharged through the entire cloud. |
density | mass/volume |
pressure | force/area |
unit for pressure | pascal (P) |
atmospheric pressure | the pressure exerted by the air |
melting point | the temperature at which a solid melts |
freezing | the changing of a liquid to a solid at the freezing point |
condensation | the changing of a gas into a liquid |
boiling | occurs below the liquids surface at the boiling point |
vaporization | changing a liquid to a gas |
melting point | the temperature at which a solid melts |
melting | changing a solid to a liquid |
