what is matter
|
anything that has mass and volume
' |
|
|
4 general properties of matter
|
mass, weight, volume, and density
|
|
|
general property
|
descirbe how all matter is the same. Quantitavie data - vol, mass, dens, weight
|
|
|
specific property
|
show how kinds of matter are different. Quantitave- color, shape
|
|
|
mass
|
the amount of matter in an object
|
|
|
wieght
|
the measure of the force of attracion between an object due to gravity
|
|
|
how do you measure mass
|
grams
|
|
|
3 factors that effect weight
|
gravity
density altitude |
|
|
4 phases of matter
|
solid
liquid gas plasma |
|
|
2 characteristics of solids
|
definate shape and volume
|
|
|
2 characteristics of liquid
|
definate volume, no definate shape
|
|
|
2 characteristics of gas
|
no definate shape or volume
|
|
|
2 characteristics of plasma
|
REALLY high in energy
cannot be contained by ordinary matter |
|
|
physical change
|
boiling water, can get back to origonal substance. phase altered but not substance
|
|
|
chemical change
|
burning wood. different substance. cannot turn ashes into origonal piece of wood
|
|
|
boyles law
|
smaller volume = greater pressure
greater volume = smaller pressure |
|
|
charle's law
|
raised tempurature = raised pressure
lowered temperature = lowered pressure |
|
|
what is a phase change
|
a subtance turning into a different type of matter.
ex: liqudi into gas (boiling) |
|
|
boiling
|
a phase change in which particles inside a liquid as well as those on the surface, change into gas
|
|
|
evaporation
|
phase change in which the suface of a liquid vaporizes
|
|
|
condensation
|
phase change in which gass turns into liquid
|
|
|
sublimation
|
phase change solid into gas
|
|
|
ho do u find density
|
d = m/v
|
