The Gas Laws Section 14.1 Objectives: 7.0 Explain the behavior of ideal gases in terms of pressure, volume, and temperature using Charles's law, Boyle's law, and Gay-Lussac's law.

KMT Review  3 Assumptions: 1.Intermolecular forces? 2.Size and space? 3.Motion?  What happens to the kinetic energy when gas particles collide?  If two gases have the same temperature, how does the average kinetic energy of the gases compare?

Boyle’s Law Lab  Boyle’s law states that the ________ of a gas varies ___________ with _____________.  This means that as volume increases, pressure ______________.  Boyle’s Law: P 1 V 1 = P 2 V 2  Give an example of application of Boyle’s law.  Example/Practice: P.422

Charles’s Law  What happens to a balloon if you put it in a warm car?  So how are temperature and volume related?  As temperature increases, volume _________.  Charles’s Law: V 1 /T 1 = V 2 /T 2  What units should you use for temperature in this equation?????  Example/Practice: P.425

Gay-Lussac’s Law  Think about the balloon again. What happens to volume if temperature increases? So what will happen to the pressure if temperature increases?  Gay-Lussac’s Law: P 1 /T 1 = P 2 /T 2  Again, what units MUST temperature be in?  Example/Practice: P.427
