Matter

TermDefinition
Matter everything around us
solid 1 shape and 1 volume
liquid no shape and 1 volume
gas particles are able to move and spread out filling all space available, thus gases have no definite shape or definite volume, gas particles constantly collide with one another and the walls of their container.
atoms makes up everything
Melting: When a solid changes to a liquid
Melting point: the temperature at which a substance melts
Freezing: When a liquid changes to a solid
Freezing point: the temperature when a substance freezes.
Vaporization: When a liquid changes to a gas
Condensation: When a gas changes to a liquid.
Sublimation: When a substance changes straight from a solid to a gas.
Surface Tension: An inward force, or pull among the molecules in a liquid that brings the molecules on the surface closer together.
Viscosity: A liquid's resistance to flowing. Example: Honey has a high viscosity.
Pressure: Pressure is the outward push divided by the area of the walls of the container. Pressure= Force/Area.
Temperature: the higher the temperature the faster particles move.
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.
Boyle's Law: When the pressure of a gas at a constant temperature is increased the volume decreases, if the temperature is decreased then the volume is increased.
Crystalline solids: particles form a regular repeating pattern called crystals. Example: salt, sugar, and snow.
Amorphous solids: particles not arranged in a repeating pattern. Example: Glass, plastic, and rubber.
Inversely proportional: When the value of one variable increases, the other decreases.
Directly proportional: as one amount increases, another amount increases at the same rate

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.
