Chemistry

Chapter 14 Definitions

TermDefinition
Boyle's Law For a given mass of gas at constant temperature, the volume of the gas caries inversely with pressure
Charle's Law The volume of a fixed mass of gas is directly proportional to its Kelvin temperature if the pressure is kept constant
Combined Gas Law The law that describes the relationship among the pressure, temperature of an enclosed gas
Compressibility A measure of how much the volume of matter decreases under pressure
Dalton's Law of Partial Pressures At constant volume and temperature, the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of the component gases
Diffusion The tendency of molecules to move toward areas of lower concentration until the concentration is uniform throughout
Effusion The process that occurs when a gas escapes through a tiny hole in its container
Gay-Lussac's Law The pressure of a gas is directly proportional to the kelvin temperature if the volume is constant
Graham's Law of Effusion The rate of effusion of a gas is inversely proportional to the square root of its molar mass
Ideal Gas Constant The constant in the ideal gas law with the symbol R and the value 8.31 (L*kPa)/ (K*mol)
Ideal Gas Law The relationship PV=nRT, which describes the behavior of an ideal gas
Partial Pressure The contribution each gas in a mixture of gases makes to the total pressure
Kinetic Theory A theory explaining the states of matter, based on the concept that all matter consists of tiny particles that are in constant 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.
