T THE IDEAL GAS The ideal Gas, Boyle’s Law, Charles’ Law, Avogadros’s Law, equation of state of an ideal gas, Dalton’s Law of Partial pressure, Joule’s Law, 3 rd Law of Thermodynamics, Gas tables and properties. The ideal gas law, as we have previously been taking up is expressed in the following equation Actual gases approach this condition when the pressure is low; and/or the temperature is high (however, not all gases approach behaviors close to the ideal gas law at the same condition of pressure or temperature) Boyle’s Law – If a gas undergoes a change of state at constant temperature. p 1 V 1 = p 2 V 2 Charles’ Law – This law consists of 2 parts: For a constant pressure process V 1 /V 2 = T 1 /T 2 and for a constant volume process p 1 /p 2 = T 1 /T 2 Avogadro’s Law – Under the same conditions of temperature and pressure, equal volumes of different gases (ideal) contain an equal number of molecules.
