properties of matter

TermDefinition
matter occupies space and has mass
element pure substance, not as common in nature, can't be seperated with chemical methods
compound made of 2 or more elements, more common in nature, can be seperated with chemical methods
mixture most common in nature, components aren't chemically combinedconsists of 2 or more elements which can retain og state, can be seperated with physical methods
homogeneous mixture a mixture in which the composition is uniform throughout
heterogeneous mixture a mixture in which the composition is not uniform throughout
sieving solid particles seperated by size
sedimentation solid particles setlle out from liquid or gas (larger at the bottom)
decanting pouring a lquid of a solid (after sedimentation)
filtration undissolved solid particles seperated from liquid or gas through a filter
evaporation used when one component evaporates faster (seperate a solute from a solution)
solute the substance that is dissolved
solvent the substance that does the dissolving
magnetic seperation used when one compenent has a higher magnetic attraction
seperating funnel used to seperate two immiscible liquids (liquids of different density)
centrifuging mixture seperated by being spun extremely fast
distillation used to extract a solvent from solution through evaporation based on boiling point
fractional distillation used to seperate components of a liquid mixture using evaporation (boiling points differ)
gravimetric analysis analysis by mass (mass percentage of each substance in a mixture)
metals lusterous
metals malleable
metals ductile
metals mostly silvery in colour
metals dense
metals high melting and boiling point (solids)
metals good conductors of heat and electricity
metalloids properties of both metals and nonmetals
non-metals dull
non-metals not malleable/brittle
non-metals most are gas at room temperature
non-metals not ductile
non-metals low density
non-metals low melting and boiling points
non-metals poor conductors of heat and electricity
non-metals

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
