Document Summary
Equation of state describes the relation between pressure, volume, and absolute temperature of a real gas: real gas: the intermolecular forces are larger. For an ideal gas, the product of pressure and volume is proportional to the absolute temperature of the gas. Under typical atmospheric temperature and pressure conditions, an ideal has law can be reasonably approximate the equation of state. Ideal gas laws: boyle"s law, the pressure of a gas is inversely proportional to its volume at constant temperature, describes compressibility of a gas. P~1/v: charles" law, at constant pressure, the volume of a gas is directly proportional to its temperature (principle behind balloons) V~t: avogadro"s law, the volume of a gas at constant temperature and pressure is proportional to the number of molecules in the gas and is independent of the type of gas. V~n: ideal gas law (simplified equation of state, pv=nrt. Where r is the ideal gas constant (r=8. 314jk-1mol-1) (joules)
