1st step of matter
|
at room temperature most substances are either a solid, liquid, or gas
|
|

|
everything that is matter is made up of particles
|
|
|
solid
|
tightly bound particles that vibrate.
wont take the shape of a container unless arranged |

moderatly strong and slide over eachother. can take the shape of a container
|
|
|
gas
|
very spacious
|
|
|
latent heat
|
heat that needs to be absorbed by a substance in order to change state this is why there are sometimes flat sections on a graph
|
|
|
variable
|
something that can change or be changed in your investigation
|
|
|
dependant variable
|
time taken to dissolve
|
|
|
controlled variable
|
something that needs to be kept the same
|
|
|
sieving
|
used to seperate a bigger solid from a liquid of another solid ed pasta and water
|
|
|
decanting
|
eg. allowing sand to settle to the bottom of the bucket and ouring out the water
|
|
|
gravity separation
|
using gravity to separate a soulution
|
|
|
evaporation
|
by heating a solution the substance will heat up and turn to steam with will then rise up into the air
|
|
|
filtration
|
used to separate solids from liquids
|
|
|
why things seperate from eachother
|
because they have different densitys
