# CFI Chemistry Gas Laws

 Dalton's Gas Law Total pressure of a mixture of gaes equals the sum of the pressures that each gas would exert if it was present alone Pt=P1+P2+P3... Avogardro's Law If you have the same volume of 2 gases, they'll have the same number of molecules Avogadro's Number 6.022 x 1023 # of particles in a molecule Boyle's Law Volume is inversely propotionate to pressure; If volume is down pressure is up P1V1 = P2V2 Charle's Law Directly proportions: As volume goes up, tempreture goes up V1/T1 = V2/T2 Gay-Lussac's Direct proportions: If pressure goes up, temperture goes up P1/T1 = P2/T2 The Combined Gas Law Charles and Boyles Law (P1V1)/T1 = (P2V2)/T2 Ideal Gas Law PV = nRT Conversion of Celcius to Kelvin Celcius + 237 = K Constant for R 0.0821 L(atm)/mol(K) Grahams Law Rate of diffusion is inversly proportionate to the square root of molecular mass Rate A/Rate B = Sq root of Molecular mass of B/Sq Root of Molecular mass of A AuthorAnonymous ID74836 Card SetCFI Chemistry Gas Laws DescriptionGas Laws Updated2011-03-23T22:53:30Z Show Answers
