states of matter
solid, liquid, gas
solid
has mass, takes up space, has definite shape
liquid
has mass, takes up space, takes shape of container
gas
has mass, takes up space, no definite shape
property of matter
volume, mass, density, boiling point....
volume
how much space matter takes up-in ml and l-liquids
mass
how much matter is in a definite space
weight
measure of gravity pulling on an object's mass-in g and kg
density
how much mass in a definite space-more gravity pulling so will be on bottom
boiling point
the temperature when of water evaporation-liquid to gas-add heat-100 degrees Celsius
freezing point
the temperature when water changes from liquid to solid-take away heat-water expands-0 degrees Celsius
melting point
the temperature when a substance changes from a solid to liquid-add heat
conduct
the ability of substances to allow heat and electricity to pass through-metals-must be connecting or touching
insulate
the ability of substances to block heat and electricity from passing through
magnetic
attracted to magnets-metals-iron and steel (iron is in steel)-poles are N and S-N to S-attracts (pulls) S to S and N to N -repels (pushes)
buoyancy
the ability to float in water
mixture
two or more solids put together-can be separated
dissolve (solubility)
a solid breaks apart in a liquid, cannot see the solid-salt or sugar in water-can be separated by evaporating the water
solution
dissolving a solid into a liquid (water)-combining two liquids
evaporate
liquid to gas-add heat
condense
gas to liquid-take away heat
freeze
liquid to solid-take away heat
melt
solid to liquid-add heat
