chariteristic prp.

characteristic properties, density, phase changes...

QuestionAnswer
characteristic properties differences between substances density, Melting point, freezing point, boiling point, condensation…a property that is always the same no matter how much of it you have
density how much space something takes up- mass/volume
phase change transitions between states of matter , pressure and temp can cause it to occur
melting point:: ------> freezing point <------
condensation:: <------ boiling point ------>
liquid fixed volume, molecules not tightly packed, medium energy, no fixed shape
pressure makes things take up less room and become less dense, force per area
solid fixed volume, molecules tightly packed, low energy,fixed shape
gas no fixed volume, molecules loosely packed, high energy,no fixed shape
sublime solid--->gas
states of matter solid, liquid, gas
sublimation::------> deposition<------
deposition gas--->solid
chromatography separation of mixtures by solubility and molecular weight
solubility how well something dissolves into something else
distillation the separation of a liquid by heating or cooling
hydrogen bonding apart of water molecules, when hydrogen is attracted to another type of atom like oxygen or nitrogen
filtration uses solubility to separate mixtures by a filter
floatation the separation of a mixture by the use of density

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.
