Chemistry Lab/Gas Laws

This page refers to the 2016 focus of Chemistry Lab.

Avogadro's Law

Avogadro's Law, also known as Avogadro's hypothesis or Avogadro's principle, says equal volumes of all gases, at the same temperature and pressure, have the same number of moles. In particular, the volume of a gas is proportional to the number of moles.

Memorization

HERE’S AN EASY WAY TO MEMORIZE ALL OF THIS! Start with the combined gas law: P1V1T2 = P2V2T1 Memorize it. Next, put the fellas’ names in alphabetical order. Boyle’s uses the first 2 variables, Charles’ the second 2 variables & Gay-Lussac’s the remaining combination of variables. What ever doesn’t appear in the formula, is being held CONSTANT!
