|
matter |
anything that has mass and takes up space |
|
|

a small particle that makes up matter |
|
|
physical property |
properties that can be observed without changing the identity of the substance
|
|
|
mass |
amount of matter in an object
|
|
|
weight |
measurement of the pull of gravity on an object
|
|
|
volume |
amount of space that matter takes up |
|
|
density |
measurement of how much mass fits in within a certain volume |
|
|
calculating density |
mass/volume |
|
|
fluids |
liquids and gases that can flow |
|
|
buoyance |
the ability of an object to float in a fluid |
|
|
Archimedes' Principle |
states that buoyant force is equal to the weight of the fluid that is displaced |
|
|
solids |
have a definite shape and occupies a definite volume |
|
|
Liquid |
have a definite volume but not a definite shape. takes the shape of the container |

melting point |
temperature at which the solid melts to become a liquid |
|
|
freezing point |
temperature at which a liquid changes to a solid |
|
|
boiling point |
temperature at which a liquid boils |
|
|
condensation |
process when a gas becomes a liquid |
|
|
vaporization |
process when a liquid becomes a gas |
|
|
chemical properties |
the ability of a substance to combine with or change into one or more new substances |
|
|
reactivity |
how easily one substance reacts with another substance |
|
|
acids |
release hydrogen ions into a solution and make litmus paper red |
|
|
bases |
turn litmus paper blue and release hydroxide ions into solutions |
|
|
neutralization |
when acids and bases combine to form salts |
|
|
physical change |
alters the form of an object without changing what type of matter it is |
|
|
chemical change |
a change in matter in which the substances that make up the matter changes into other substances |
|
|
precipitate |
a solid that sometimes forms when two liquids combine |
|
|
chemical bonds |
forces that hold atoms together |
|
|
chemical reaction |
process that produces chemical change, resulting in new substances that have properties different from those of the original substances |
|
|
reactants |
substances that exist before the reaction happens and on the left side of an equation |
|
|
products |
substances that form as a result of the reaction and on the right side of an equation |
|
|
Chemical equation |
shorthand way to write a chemical equation |
|
|
law of conservation of mass |
matter cannot be created nor destroyed |
