matter

TermDefinition
Solid: Solid: closely packed particles cause matter to have a definite shape and definite volume.
Crystalline solids: Crystalline solids: particles form a regular repeating pattern called crystals.
Amorphous solids: Amorphous solids: particles not arranged in a repeating pattern.
Liquid: Liquid: particles are free to move so a liquid has a definite volume but no definite shape.
Surface Tension: Surface Tension: An inward force, or pull among the molecules in a liquid that brings the molecules on the surface closer together.
Viscosity: Viscosity: A liquids’s resistance to flowing.
Gas: Gas: particles are able to move and spread out filling all space available, thus gases has no definite shape or definite volume.
Pressure: Pressure: gas particles constantly collide with one another and the walls of their container. Pressure is the outward push divided by the area of the walls of the container.
Temperature: Temperature: the higher the temperature the faster particles
Melting: Melting: When a solid changes to a liquid
freezing: Freezing: When a liquid changes to a solid
Freezing point: Freezing point: the temperature when a substance freezes.
Melting point: Melting point: the temperature at which a substance melts.
Vaporization: Vaporization: When a liquid changes to a gas
Evaporation: Evaporation: takes place only on the surface of the liquid.
Boiling: Boiling: When vaporization occurs both below the and at the surface.
Boiling Point: Boiling Point: Temperature at which a liquid boils.
Condensation: Condensation: When a gas changes to a liquid.
Sublimation: Sublimation: When a substance changes straight from a solid to a gas.
Charles’s Law: Charles’s Law: When the temperature of a gas at a constant pressure is increased the volume is increased, if the temperature is decreased then the volume is decreased.
Directly proportional: Directly proportional: as one amount increases, another amount increases at the same rate.
Boyles Law: Boyles Law: When the pressure of a gas at a constant temperature is increased the volume is decreases, if the temperature is decreased then the volume is increases.
Inversely proportional: Inversely proportional: When the value of one variable increases, the other decreases.

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.
