phases of matter

termdefinition
solid state of matter in which the particles of matter are closest together, having a definite shape and a definite volume.
liquid state of matter in which the particles are free to move over, under and around one another;particles are farther apart than in a solid. liquids have no definite shape and a definite volume.
gas state of matter in which the particles are moving the fastes and are the farthest away from each other. gases have no definite shape and no definite volume.(fits the container)
plasma state of matter that is achieved under very high temperatures, no definite shape. plasma have no definite shape and atoms have been ripped apart. ex:stars, tv's, and lightning.
kinetic molecular theory the theory that explains differences in the states of matter are caused by how fast the atoms in substances are moving (called kinetic energy). slow=solid faster=liquid super fast= gas super super fast=plasma
endothermic physical changes in which energy is absorbed, the temperature of the substance changes.
exothermic physical change in which energy is released,the temperature of the substance changes.
melting the phase change from asolid to a liquid material to must gain energy (temperature=increase) endo= heat insides
melting point the temperature at which a substance begins to melt the melting point of water is 32
freezing the phase change from a liquid to a solid,material must lose energy (temperature=decreases)
freezing point the temperature at which a substance begins to melt.the freezing point of water is 32c and 0c
vaporization phase change from a liquid to a gas , material must gain energy (temperature = increase) endo=heat inside
evaporation phase change from a liquid to a gas at the surface of liquid below the boilling point.
boilling the phase change from a liquid to a gasthroughout the entire liquid. endothermic
boilling point the temperature at which a substance begins to boil. the boilling point of water is 212f, 100c
condensation the change in phase from a gas to a liquid, material requires a loss of energy(temperature=decreases)
sublimation the change in phase from a solid to gas without going through theliquid phase. endothermic
deposition phase change froma gas to a solid without going through the liquid phase (frost) exothermic.

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.
