 Topic: Ideal Gas Law  Date: 5/14/2013  (P,V) are inversely related.  (P,T) and (V,T) are directly related. Combined Gas Law Boyle’s P 1 V 1 = P 2 V 2 Lussac’s P 1 = P 2 T 1 T 2 Charles’ V 1 = V 2 T 1 T 2 Combined Gas Law = P 1 V 1 = P 2 V 2 T 1 T 2

 Topic: Ideal Gas Law  Date: 5/13/2013  Avogadro’s Principle (1811)  An observation that is an extension of KMT  All gases are assumed to have the same particle size.  Equal volume of 2 gases will have the same # of particles! Avogadro’s Principle Amedeo Avogadro For any gas: 6.02 x particles = 22.4 L 1 mol 1 mol

 Topic: Ideal Gas Law  Date: 5/13/2013  Ideal Gas Law relates pressure (P), volume (V), temperature (T) and number of moles (n) of gas. Ideal Gas Law P V = n R T Pressure of gas (atm) Volume of gas (L) Temp. of gas (K) Moles of gas (mol) Gas constant (L ·atm/mol·K )

 Topic: Ideal Gas Law  Date: 5/13/2013 Practice Problem: A 2.0L sample of gas has a pressure of 1.5atm. If 5.0 moles occupy the sample, what is the temperature? Example PV = nRT (1.5)(2.0) = (5.0)(0.0821)x 3 = (0.4105)x x = 3/ x = 7.308K = T P = 1.5atm V = 2.0L n = 5.0mol R = L·atm/mol·K T = x

Reflection  In your notes answer the following question: How can you predict how a gas will be affected in a given situation? (in terms of P, V, n, and T)
