Chemistry Honors Gas Laws Guide The “ABC” gas laws (Avogadro, Boyle, Charles) all deal with volume. (ABC, nPT) STP means standard temperature and pressure (ideal conditions from Kinetic Molecular Theory). Temperature is 0° C (273 K) and pressure is 1 atm. K = C + 273 C = 9/5 F + 32 Units of Pressure 1 atm (atmosphere) = 760 mm Hg = 760 torr = 101325 Pa (Pascals) = 14.7 p.s.i. Units of Volume 1 L = 1000 mL = 1000 cm 3 Avogadro’s Law Avogadro gave us the mole ! So his gas law deals with volume and number of moles, assuming that pressure and temperature are constant. As the number of moles increases, the volume also increases (proportional). V 1 / n 1 = V 2 / n 2 Boyle’s Law Boyle’s law tells us the relationship between pressure and volume, assuming that number of moles and temperature remain constant. This law is useful for scuba diving. As the pressure increases the volume decreases (inversely proportional). P
