This document summarizes three gas laws: Boyle's Law which relates pressure and volume, stating that as pressure increases, volume decreases; Charles's Law which relates temperature and volume, such that increasing temperature increases volume; and Gay-Lussac's Law which relates pressure and temperature, with increasing temperature also increasing pressure. It also introduces Avogadro's Law relating the volume and number of moles of gas at constant temperature and pressure conditions.
