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
