Chapter 13 - Gas Laws Flashcards
A measure of the total amount of force divided by the surface area over which it is exerted.
pressure
An instrument used to measure pressure.
barometer
The pressure exerted by the weight of the atmosphere at a given altitude.
atmospheric pressure
A common unit of pressure originating from the mercury barometer
millimeters of mercury (mm Hg)
A unit of pressure equal to mm Hg named after Italian physicist Evangelista Torricelli.
torr
States that for a fixed amount of gas at a constant temperature, the volume occupied is inversely proportional to its pressure.
Boyle’s Law
The lower limit for possible temperatures, a value of 0 Kelvin or -273°C
absolute zero
States that for a fixed amount of gas at a constant pressure, the volume is directly proportional to its absolute temperature
Charles’s Law
States that pressure is directly proportional to the absolute temperature
Gay-Lussac’s Law
States that if you compare two samples of an ideal gas at the same temperature, pressure, and volume, they contain the same number of molecules.
Avogadro’s Law
The equation of state that describes the relationship between temperature, pressure, volume, and amount of an ideal gas. Derived from a combination of Boyle’s, Charles’s, Gay-Lussac’s and Avogadro’s gas laws.
