chemistry gas laws review

Boyle’s law

pressure and volume of gases in a constant temp. are inversely proportional

Charles law

temp. (K) and volume are directly proportional when pressure and gas are constant

Gay-Lussac’s Law

pressure of a fixed gas at constant volume varies directly with the Kelvin temperature

Pressure =

Force/Area

Combined gas law

relationship among the pressure, temperature, and volume of an enclosed gas (CONSTANT)

Dalton’s law of partial pressure

the total pressure of a gas mixture is equal to sum of the partial pressures

Avogadro’s law

equal volumes of gases at the same temperature and pressure contain equal numbers of molecules.

STP

standard temperature and pressure

Ideal gas law

relationship between pressure, volume, temperature and the number of moles in a gas

What makes an ideal gas?

high temperatures and low pressure

Graham’s law of diffusion

rate of effusion of a gas is inversely proportional to the square root of the gas’s molar mass.

What is a barometer?

a tool that measures atmospheric pressure using mercury

Boyle’s law (equation)

P₁V₁=P₂V₂

Charles’s law (equation)

V₁/T₁=V₂/V₁

Gay-Lussac’s Law

P₁/T₁=P₂/T₂

Combined gas law (equation)

P₁V₁/T₁=P₂V₂/T₂

Ideal gas law (equation)

PV=nRT

Molar mass (equation)

M=mRT/PV

Density (equation)

D=MP/RT

Graham’s law of effusion

√High/√Low

Dalton’s law of partial pressure

P_T=P₁+P₂+P₃……

Effusion

gas escapes through tiny hole, lower molar mass causes faster diffusion/effusion

Kinetic Theory of gases

based off belief that particles are always in motion
