ideal gas laws

Boyles Law

At constant temperature, the volume of a fixed mass of gas is inversely proportional to its pressure

charles law

at a constant pressure the volume of a fixed mass of gas is directly proportional to its temperature measure on the kelvin scale

relative molecular mass

the average mass of one molecule of the compound compared to 1/12th the mass of a carbon-12 isotope

Gay-Lussac's Law

the pressure of a gas is directly proportional to the Kelvin temperature if the volume is constant

what conditions are you real gases closest to ideal

high temperature and low pressure

Avogadro's Law

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

Ideal Gas

A gas that obeys all the assumptions of the kinetic theory of gases under all conditions of temperature and pressure

diatomic molecule

A molecule consisting of two identical atoms (meaning identical mass)

real gases

particles have volume

energy is lost in collisions

intermolecular forces

ideal gases

particles have no volume

collisions are elastic

no interaction between particles

Ideal Gas Equation

pV=nRT
