In a number of applications, a chemist has to deal with all three gas variables changing. As a result, Boyle's, Charles' and Gay-Lussac's laws have been combined into one equation, called the Combined Gas Law. P1V1/T1 = P2V2/T2. Avogadro's principle states that equal volumes of gas at the same temperature and pressure contain equal numbers of particles. This quiz will cover simple combined gas law and Avogadro's Principle problems. You will need a calculator. Select the best answer from the choices.
