Chapter 2 Section 1

Science Explorer

freezing the change of state from a liquid to a solid
melting the change of state from a solid to a liquid
vaporization the change of state from a liquid to a gas
evaporation vaporization that only takes place on the surface of a substance
boliling vaporization that occurs throughout the substance, including the surface
condensation the change of state from gas to liquid
sublimation The change of state directly from solid to gas, without going through the liquid phase
boiling point The temperature at which a liquid boils
melting point The specific temperature in which a substance melts
solid A substance that has a definite shape and volume
crystalline solid solids that are made up of crystals, when it is heated up, it melts at a certain temperature
amorphous solid a solid in which the particles are not arranged in a regular pattern, when an amorphous solid is heated it just gets softer and softer
liquid A substance that doesn't have a definite shape but has a definite volume
fluid A substance that flooows, can include liquids AND gases
surface tension The result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together; a property of liquids
viscosity a liquid's resistance to floooowing
gas a substance that doesn't have a definite volume or shape
charles law #1 a law that states as temperature increases, volume increases as temperature decreases, volume decreases in a gas at constant pressure
boyles law a law that states that as pressure increase volume increases as pressure decreases volume increases in a gas at constant temperature
charles law #2 a law that states as pressure increases, temperature increases as pressure decreases, temperature decreases in a gas at constant volume
Charles Law #2 Formula P1/V1 = P2/V2 where P1 = 1st Pressure, P2 = 2nd Pressure V1 = 1st Volume and V2 = 2nd Volume
Boyles Law Formula PV = k, where p = pressure, v = volume, and k = the gas constant
Ideal Gas Formula PV = nrt where p = pressure, v = volume, n = amount of moles in the gas r = the gas constant and t = temperature
Pressure Force/Area

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.
