#### Definitions

Diffusion process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated
Effusion flow under pressure
elastic collision a collision in which there is no net loss of total kinetic energy
fluid a continuous amorphous substance that tends to flow and to conform to the outline of its container: a liquid or a gas
ideal gas a hypothetical gas with molecules of negligible size that exert no intermolecular forces
kinetic-molecular theory the theory that all matter is composed of particles (atoms and molecules) moving constantly in random directions
real gas a gas that does not behave completely according to the assumptions of the kinetic-molecular theory
atmosphere of pressure the pressure of Earth's atmosphere at sea level; exactly equivalent to 760 mm Hg
barometer an instrument that measures atmospheric pressure
millimeter of mercury A unit of pressure; it is the pressure needed to support a column of mercury one millimeter high
newton the SI unit of force
pascal a unit of pressure equal to one newton per square meter
pressure the force applied to a unit area of surface
STP 0 degrees C and 1 atm
absolute zero (cryogenics) the lowest temperature theoretically attainable (at which the kinetic energy of atoms and molecules is minimal)
Boyle's Law The relationship between the pressure and volume of a gas at constant temperture; when volume increase, pressure decreases., P1V1=P2V2
Charles'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 relationship between the pressure, volume, and temperature of a fixed amount of gas, P1V1/T1 = P2V2/T2
Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the pressures of all the gases in the mixture
gas laws the laws that state the mathematical relationships between the volume, temperature, pressure, and quantity of a gas
Gay-Lussac's law the law that states that the pressure of a gas at a constant volume is directly proportional to the absolute temperature, P1/T1=P2/T2
partial pressure the pressure of each gas in a mixture
