volume, mass, density, boiling point....
how much space matter takes up-in ml and l-liquids
how much matter is in a definite space
measure of gravity pulling on an object's mass-in g and kg
how much mass in a definite space-more gravity pulling so will be on bottom
the temperature when of water evaporation-liquid to gas-add heat-100 degrees Celsius
the temperature when water changes from liquid to solid-take away heat-water expands-0 degrees Celsius
the temperature when a substance changes from a solid to liquid-add heat
the ability of substances to allow heat and electricity to pass through-metals-must be connecting or touching
the ability of substances to block heat and electricity from passing through
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)
the ability to float in water
two or more solids put together-can be separated
a solid breaks apart in a liquid, cannot see the solid-salt or sugar in water-can be separated by evaporating the water
dissolving a solid into a liquid (water)-combining two liquids
liquid to gas-add heat
gas to liquid-take away heat
liquid to solid-take away heat
solid to liquid-add heat
