properties of gases

Gas

substance that has no well defined boundaries but diffuses rapidly to fill any container in which it's placed

Boyle's Law

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

Charle's Law

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

Gay Lussac's Law of combining gases

in a reaction between gases, the volume of the reacting gas and the volume of any gaseous product are in the ratio of small whole numbers, provided the volumes are measured at the same temperature and pressure

STP

273K/0C 100kPa

Combined Gas Law

pv/t = pv/t

Avagadro's Law

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

Ideal Gas

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

Ideal gas equation

PV = nRT
