### Chapter 14: Gases

14.1 The Gas Laws
Kinetic theory
Boyle’s Law: P1V1= P2V2 (inversely proportional)
Charles's Law: V1/T1 = V2/T2
Gay-Lussac’s Law P1/T1 = P2/T2

14.2 The Combined Gas Law and Avogadro’s Principle
combined gas law
(P1V1) / (n1T1) = (P2V2) / (n2T2)
molar volume means – 1mole of any gas at STP = 22.4 L

14.3 The Ideal Gas Law
PV = nRT the constant R depends on units of measure used for variables

Real vs ideal gases - For an ideal gas: (a) gas particles take up no space; (b) there are no intermolecular forces; follows the gas laws under all temp. and pressures conditions. There is no ideal gas, you can only get close. You get closest to ideal at VERY LOW pressures and HIGH temperatures.

Below are 2 videos recorded today to help understand how to do problems 4/30/2019 VIDEO LINK - How to work problems p 432 24 - 27 4/30/2019 VIDEO LINK - How to work problem 28, and how to make your own gas laws 5/1/2019 VIDEO LINK - problem 32 - whcih is unique to this set of problems because you cannot use GIVEN or FIND. 5/1/2019 p433 29-33 5/1/2019 VIDEO LINK - problem # 33 - is like problems 29, 30, & 31 because you can solve using given & find and using unit cancellations string of fractions
