manometer

Front

a device for measuring the pressure of a gas in a container

Back

pascal

Front

the SI unit for pressure; equal to newtons per meter squared

Back

Graham's law of diffusion

Front

the rate of effusion of a gas is inversely proportional to the square root of the mass of its particles

Back

mm Hg

Front

a unit of pressure, also called a torr

Back

universal gas constant

Front

R - the combined proportionality constant in the ideal gas law

Back

ideal gas law

Front

PV = nRT

Back

partial pressure

Front

the independent pressures exerted by different gases in a mixture

Back

standard atmosphere

Front

a unit of pressure equal to 760 mm Hg

Back

torr

Front

another name for mm Hg

Back

Avogadro's law

Front

equal volumes of gases at the same temperature and pressure contain the same number of particles

Back

Dalton's Law of Partial Pressures

Front

for a mixture of gases in a container, the total pressure exerted is the sum of the pressures that each gas would exert if it were alone

Back

molar volume

Front

the volume of one mole of an ideal gas; equal to 22.42 L at STP

Back

mole fraction

Front

the ratio of the number of moles of a given component in a mixture to the total number of moles in the mixture

Back

barometer

Front

a device for measuring atmospheric pressure

Back

standard temperature and pressure (STP)

Front

the condition of O degrees C and 1 atmosphere of pressure

Back

Charles's law

Front

the volume of a given sample of gas at constant pressure is directly proportional to the temperature in kelvin

Back

diffusion

Front

the mixing of gases

Back

kinetic molecular theory (KMT)

Front

a model that assumes that an ideal gas is composed of tiny particles (molecules) in constant motion

Back

ideal gas

Front

a gas that obeys the ideal gas law

Back

Boyle's Law

Front

the volume of a given sample of gas at a constant temperature varies inversely with the pressure

Back

absolute zero

Front

O K; where the volumes of the gases extrapolate to zero

Back

effusion

Front

the passage of a gas through a tiny orifice into an evacuation chamber

Back

van der Waals equation

Front

a mathematical expression for describing the behaviour of real gases

Back

root mean square velocity

Front

the square root of the average of the squares of the individual velocities of gas particles...

Back

joule

Front

kg m2 / s2

Back
