matter
|
anything that has mass and takes up space
|
|
states of matter
|
solid, liquid, gas
|
|
mass
|
the amount of matter contained in an object
|
|
mass
|
it is always the same everywhere in the universe
|
|
weight
|
the measure of the pull of gravity on an object
|
|
weight
|
depends on where you are in the universe
|
|
density
|
the concentration of matter in an object
|
|
density
|
determined by the formula
d = m/v density = mass/volume |
|
volume
|
the amount of space an object takes up
|
|
volume
|
two methods to find this:
1) measure, then use formula V = l x w x h or 2) water displacement method |
|
physical property
|
the characteristics of a substance that identifies that substance; these can be observed without changing the substance
|
|
examples of physical properties
|
density, color, texture, odor, shape, size, luster, hardness, transparency, state of matter, freezing point,etc
|
|
solid
|
made up of molecules that are tightly connected; they have a definite shape, size, and volume
|
|
liquid
|
made up of molecules that are loosely conected; they have a definite volume but no definite shape
|
|
gas
|
made up of molecules that are not connected; they have no definite size, shape, or volume
