The+Combined+Gas+Law-+M.Killeen

The Combined Gas Law was a law that was created, and used after CHarle's, Boyle's and Gay-Lussac's Laws were all known to chemitsts to be accurate and true. This combined law is used dealing with the reality that a gas will be under the influence of each aspect of the those three laws made before (pressure, temperature and volume), whereas the three laws before had only involved two out of the three variables. The formula of the Combined Gas Law is:

P1 V1 / T1 = P2 V2 / T2
