Gas The State of Matter in which there is no definite shape or volume. Particles move very quickly
Plasma High-Energy state of matter in which particles are ionized or charged. Consists of ions and electrons
Melting The phase change from a solid to a liquid
Freezing The change of state from a liquid to a solid
Evaporation The change of state from liquid to gas; occurs at a temperature lower than the boiling point
Vaporization The change of state from liquid to gas, at the boiling point
Condensation The change of state from a Gas to a Liquid
Sublimation The change in state from a solid directly to a gas
Deposition The change of state from a gas directly to a solid
Boiling Point / Condensation Point The temperature at which a substance transitions between a liquid and gas.
Melting Point / Freezing Point The temperature at which a substance transitions between a solid and liquid.
Kinetic Energy The energy of an object due to an object’s motion; measured in Joules
Temperature A measure of the average kinetic energy of the particles in an object; measured in *F, *C, or K
Thermal Energy The Total kinetic energy of all the particles in a sample; measured in Joules
Kinetic Molecular Theory Theory based on the idea that all matter is made up of tiny particles that are always in motion.

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.
