Matter
| Term | Definition |
|---|---|
| matter | anything that has mass and takes up space |
| particle | a very small unit(piece) that makes up matter |
| classify | to group, or sort |
| physical property | characteristics that can be tested, measured or observed |
| mass | the amount of matter in a material, in grams (1 paperclip = 1 gram) |
| volume | the amount of three-dimensional space an object takes up or contains, in math volume = l x w x h |
| magnetism | attraction to a magnet (INCS - iron, nickel, cobalt and steel) |
| thermal energy | energy that is transferred from one substance to another as the result of a difference in temperature, the hotter the substance, the more its particles move |
| electric energy | a form of energy produced by the flow of charged particles, such as electrons, through a conductor |
| conductor | an object that ALLOWS energy to pass through |
| insulator | an object that DOES NOT ALLOW energy to pass through |
| soluble | dissolves in water |
| insoluble | does NOT dissolve in water |
| ingredient | a single part of a mixture |
| melt | to change from a solid to a liquid state by heat |
| attract | to pull towards |
| relative density | whether matter sinks or floats in water |
| physical state | whether matter is solid, liquid, or gas |
| solid | a state of matter with a definite shape and a definite volume, and particles that are packed very close together |
| liquid | a state of matter with a definite volume and NO definite shape, and particles that are close to each other but can slide past one another |
| gas | a state of matter with NO definite shape and NO definite volume, and particles that are very spread out |
| mixture | a combination of two or more materials that can be separated easily |
| solution | a mixture where one thing dissolves completely into another, like sugar into water |
| dissolve | to mix with a liquid until it becomes part of the liquid and you can't see it anymore because it has become evenly dispersed |
| evaporation | to change from a liquid to a gas as a result of warming, creating vapor |
| maintain | to keep, or to stay the same |
| conservation of matter | the same amount of matter exists before and after the change, none is created or destroyed |
| expand | an increase in the volume of a substance while the mass stays the same |
| contract | a decrease in the volume of a substance while the mass remains the same |
| dispersed | to spread out or scatter in different directions |
| dilute | to make thinner, weaker or less strong by adding water |
| solute | the substance that gets dissolved (example - salt or sugar) |
| solvent | the liquid that does the dissolving (example - water) |
| temperature | the measure of how hot or cold a substance it |
| boiling point | the temperature at which a liquid rapidly changes to a gas, 100'C |
| freeze | to change from a liquid to a solid |
| freezing point | the temperature at which a liquid changes to a solid, 0'C |
| condensation | to change from a gas to a liquid as result of cooling |
| boil | to rapidly evaporate |
| water vapor | water that has changed into a gas as a result of heating |
