So far, we have learned of three laws that describe the behavior of gases. They are Boyle's Law, Charles's Law, and Avogadro's law. These relationships show how volume of a gas depends on pressure, temperature, and number of moles present. They can be combined, represented by the equation V = R([Tn]/P), where R is the combined proportionality constant called the universal gas constant. When pressure is in atmospheres and volume is in liters, R has the value of 0.08206 L atm/K mol. The above equation can also be rearranged to what is known as the ideal gas law, PV = nRT. When using this equation, remember to convert pressure to atmospheres, volume to liters, temperature to kelvins, and amount present to moles. Practice Problems 1 Practice Problems 2 |
