1)Classifying Matter

5th grade science

TermDefinition
Boiling Point the temperature at which a substance changes from the liquid state to the gas state (water vapor); for water this is 100*C
conductor a substance or object that allows that allows energy to flow through it EASILY
dissolving/solubility the process by which substances breakdown into small pieces and spread out evenly in a liquid (water)
electrical energy energy that is carried by an electric circuit
freezing point the temperature that a substance changes from the liquid state to the solid state by taking away heat; for water this is 0*C
insulator a substance or object that does NOT allow energy to flow through it
the 4 magnetic metals SINC: Steel, Iron, Nickel, Cobalt
mass the amount of matter in an object; measured in grams by using a triple beam balance
matter anything that has MASS and takes up space
relative density floating or sinking in water
Physical states (also called States of Matter) solids, liquids and gases
mixtures two or more substances that can be EASILY separated AND each substances KEEPS their physical properties
solution a type of mixture in which one or more substances are evenly spread out throughout the other substance
volume the amount of space an object takes up
magnetism a force of attraction (attract) or repulsion (repel) that causes a magnetic material to move
melting point the temperature at which a substance changes from a solid to a liquid by the addition of heat; for water this is 0*C
solid a state of matter in which the matter has a definite shape and volume
liquid a state of matter in which the matter takes the shape of its container and has volume; it has the ability to pour
gas a state of matter in which the matter spreads out to fill the space it is in
melting to add heat to change a solid into a liquid
evaporation to add heat to change a liquid into a gas
freezing to take away or remove heat to change a liquid into a solid
condensation to take away or remove heat to change a gas (water vapor) into a liquid
classifying grouping matter based on its physical characteristics
physical properties characteristics of matter: examples-color, shape, size, is it magnetic or not, does it sink or float in water, will it dissolve in water
