Matter

TermDefinition
Melting When a solid turns into a liquid
Freezing When a liquid changes into a solid
Vaporization When a liquid turns into a gas
Evaporation When only the surface of a liquid turns into a gas
Condensation When a gas turns into a liquid
Sublimation When a solid turns straight into a gas
Boiling When evaporation occurs both at the surface and the bottom of a liquid
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 as one amount increases, another amount increases at the same rate.
Boyle's 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 When the value of one variable increases, the other decreases.
Boiling Point Temperature at which a liquid boils.
Freezing point the temperature when a substance freezes.
Melting point the temperature at which a substance melts.
Temperature the higher the temperature the faster particles moving.
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. Pressure= Force/Area.
Gas particles are able to move and spread out filling all space available, thus gases has no definite shape or definite volume.
Viscosity A liquid's resistance to flowing. Example: Honey has a high viscosity.
Surface Tension An inward force, or pull among the molecules in a liquid that brings the molecules on the surface closer together.
Liquid particles are free to move so a liquid has a definite volume but no definite shape. A. Properties of Liquids:
Amorphous solids particles not arranged in a repeating pattern. Example: Glass, plastic, and rubber.
Crystalline solids particles form a regular repeating pattern called crystals. Example: salt, sugar, and snow.
Solid closely packed particles cause matter to have a definite shape and definite volume. A. Types of Solids:

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.
