1)Classifying Matter
5th grade science
Term | Definition |
---|---|
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 |
