gases

TermDefinition
Pressure The force per unit area on a surface
Newton 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 pressure.
Millimeters of Mercury the common unit of pressure is millimeters of mercury, symbolized mm Hg.
Atmosphere of Pressure defined as being exactly equivalent to 760 mm Hg.
Pascal The pressure exerted by a force of one newton acting on an area of one square meter.
Partial Pressure The pressure of each gas in a mixture.
Dalton's law of partial pressure the total pressure of a gas mixture is the sum of the partial pressures of the component gases.
Boyles Law 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 kelvin temperature scale.
Charle's law 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's law equal volumes of gases at the same temperature and pressure contains equal numbers of molecules
Standard molar volume of a gas The volume occupied by one mole of a gas at STP
ideal gas law the mathematical relationship among pressure , volume , temperature , and the number of moles of a gas.
ideal gas constant In the equation representing the ideal gas law , the constant R is known as the ideal gas constant
Graham's law of effusion the rates of effusion of gases at the same temperature and pressure are inversely proportional to the square roots to 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.
