TermDefinition
pressure pressure is defined as the force per unit area on a surface
newton the newton is the force that will increase the speed of a one-kilogram mass by one meter per second each second that the force is applied
barometer a device used to measure atmospheric presssure
millimeter of mercury the common unit of pressure
atmosphere of pressure defined as being exactly equivalent to 760 mm Hg
pascal the SI unit of pressure ; equal to the force of 1 N exerted over an area of 1 m2
partial pressure the pressure of each gas in a mixture
Dalton law of partial pressure the law that states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases
Boyle's law states that the volume of a fixed mass of gas varies inversely with the pressure at constant temperature
absolute zero the lowest possible achievable temperature is assigned the value of zero on the Kevin temperature scale
Charles's Law states that the volume of a fixed mass of gas at constant pressure varies directly with the temperature in Kelvins
Gay - Lussac's Law the pressure of a fixed mass of gas at constant volume varies directly with the temperature in kelvins
combined gas law expresses the relationship between pressure, volume, and temperature of a fixed amount of gas
Avogadro Law states that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules
standard molar volume of a gas it has been found to me 22.414 10 L
ideal gas law the mathematical relationship among pressure, volume, temperature, and the number of moles of a gas
ideal gas constant its value depends on the units chosen for pressure, volume, and temperature
Graham's law of effusion states that the rates of effusion of gases at the same temperature and pressure are inversely proportional to the square roots of their molar masses

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.
