Ideal gas-unlike a real gas, does not condense to a liquid at low temps, does not have forces of attraction or repulsion between particles and is composed of particles that have no volume. R=8.314 L X KPa R=0.0821 L X atm R=62.4 torrHgmm X L Mol X K mol X K mol X K Standard pressure-1 atm, 22.41 L, 101.325 KPa, 0.00C PV=nRT R=gas constant absolute zero—273.15C Gaseous molecules, including the molecules of compounds responsible for the smell, travel at high speeds in all directions and mix quickly with molecules of gases in the air is diffusion. Diffusion - movement of particles from regions of higher density to lower density. Effusion - the passage of gas particles through a small opening. Graham - found at constant temp and pressure, rate of effusion is inversely proportional to

Particles of low molar mass travel faster than heavier particle Gay-Lussacs law of Combining volumes-if pressure and temp. were constant gases react in volume proportions that are small whole #’s. 1 Vol H=1 Vol Cl Partial pressure-pressure exerted of each gas in a mixture Dalton’s law of partial pressure-total pressure of a mixture of gases is the sum of the partial pressures of the gases. Each exerts their own pressure. Ptotal=Pa+Pb+Pc+Pd Ideal gas- gas that follows the gas laws at all conditions of pressure and temp. Real gas-a gas that can be liquefied by applying pressure...
