Gas Laws

Gas Laws

1. Decompression

   • Molecular Collision
     • Low and High Pressure
       • Earth's Atmosphere Pressure

2. Pressure Units

   • Common unit of Pressure (mmHg)
     • 1 mm Hg = 1 torr
       • 1 atom = 760 mm Hg
         • SI unit of Pressure (Pa)
           • Boyle's Law formula
             • Pressure Increase as Volume Decrease
               • Boyle's and Hooke observed the relationship between Volume and pressure Increase and decrease
                 • Charles' Law
                   • assumes constant pressure and constant amount of gas
                     • Charles' Law Formula : V X T (constant P and n
                       • Volume and Temperature are linearly realtaed
                         • Avogardo's Law: Volume and amount in moles
                           • as amount of gas Increase , volume decrease
                             • volume Increase direct proportion, greater number of gas particles fill more space
                               • The Ideal Gas Laws
                                 • Boyle's Law, Charles' Law and Avogardo
                                   • volume X n T/P
                                     • The Volume of a gas direct proportional to the # moles
                                       • Temperature of the gas, Inversely proportional to the pressure of gas
                                       • Applicatio of the Ideal Gas Law
                                         • Molar, Volume, Density, and Molar Mass of Gas
                                           • Molar volume at Standard Temperature
                                             • Density of a gas = D = Molar Mass/ molar volume
                                               • Molar Mass of a Gas
                                                 • Molar Mass = Mass (m) / Moles of m)
                                                   • Dalton's Law of Partial Pressure
                                                     • Mixtures of Gas and Partial Pressure
                                                       • the pressure due to any component in a gas mixture is it partial pressure
                                                         • Formula for Partial Pressure = Pn = Nn RT/V
