Unit:8 gases

TermDefinition
pressure the amount of force exerted per unit area of a surface
newton the Si unit of force;the force that will increase the speed of a 1 kg mass by 1 m/s each second that the force is applied etc
barometer an instrument that measures atmospheric pressure
millimeters of mercury a unit of pressure
atmosphere f pressure the pressure of earth's atmosphere at sea level 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's law or 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
Boyles law the law that states that for a fixed amount of gas at a constant temperature, the volume of the gas increases as the pressure of the gas decreases as the pressure of the gas increases
absolute zero the temperature at which all molecular motion etc.
Charle's law the law that states that for a fixed amount of gas at constants pressure, the volume of the gas increases as the temperature of the gas increases as the temperature of the gas increases
gay-lussac's law the law that states that the volume occupied by the gas at national to the absolute temperature
combined gas law the relationship between the pressure, volume, and temperature of fixed amount of gas
avogadro's law the law that states that equal volumes of gases the same temperature and pressure contain equal numbers of molecules
standart molar volume of a gas the volume occupied by one mole of a gas stp.
ideal gas law the law that states the mathematical relationship of pressure volume temperature the gas constant and the number of mole of a gas
ideal gas constant the proportional constant that appears in the equation of state for 1 mol of an ideal gas
Graham's law of effusion the law that states that the rate of effusion of a gas is inversely proportional to the square root of the gas's density

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:
