 Kinetic Molecular Theory -gases operate like fluids -particles in constant rapid motion - all collisions perfectly elastic elastic particles completly transfer energy in elastic incomplete energy transfer green house gases trap energy from sun Avogadro's Law equal volumes of gaseshave the same number of particles at the same temperature and pressure pressure the force exerted per unit area force/area Role of ozone and chlorofluorocarbons in the upper atmosphere OZONE-protect atmosphere from being blown up CHLORO- destroy the ozone Ideal Gases High pressure Low Temperature Real Gases Low pressure High Temperature Boiling Point A liquid boils when vapor pressure within the liquid is equal to the external pressure atmosphere pressure=vapor pressure Sublimation change of state from solid to a gas relationship between: volume, pressure volume increases as pressure rises relationship between: temperature, pressure increase in temp, increase in pressure relationship between: temperature, volume increase temp, decrease volume relationship between: volume, pressure, temp increase volume, decrease pressure and temperature Barometer instrument that measures pressure using mercury Volume to Volume Calculation use 22.4 Gas diffusion area of higher concentration to area of lower concentration Boyles Law inverse relationship between pressure and volume P1V1=P2V2 Temp & Pressure Law Temperature and Pressure are directly proportional P1 P2 -- = -- T1 T2 Charles Law the relationship between temperature and volume V1 V2 -- = -- T1 T2 Combined Gas Law P1V1T2 = P2V2T1 Ideal Gas Law combination of Charles', Avogadro's, and Boyles law. PV = nRT R = 8.314 L*kPa/mol*k Dalton's Law total pressure in a gaseous system is the sum of the individual partical pressures PT = P1+P2+P3+P4+ECT...
