The Gas Laws Boyle’s Law: V = k /P Charles’s Law: V = b T Avogadro’s Law: V = a n There are three important mathematical laws that relate the properties of a gases. These were derived from experiments that involved careful measurements of relevant gas properties. The three laws are: These three laws can be brought together into one comprehensive law: The Ideal Gas Law

The Ideal Gas Law Therefore, V = (k x b x a) (nT/P) = R (nT/P) = nRT/P constants V = L (liters, convert from ml, cm 3 ) T = K (Kelvin, convert from o C) n = moles (convert from mass, etc.) P = atm (convert from torr, mm Hg, bars, pascals, etc.) If we combine the laws we get: R, the universal gas constant , equals 0.08206 LatmK -1 mol -1 : Watch your units!!
The ideal gas law is an equation of state for a gas and provides the conditions of gas at a particular time. A particular state of a gas is described by its pressure, volume, temperature and number of moles and a gas can be completely defined by knowing any three of these properties. Works best for low P (< 1 atm), and high T (> room temp)
