  1. Warm Up October 21, 2013 Mrs. Hurwitz has an uninflated balloon. She fills the balloon with a gas and ties it closed. When she lets go, the balloon floats up into the sky. She wonders what happened to the mass of the balloon. What do you think? • The floating balloon has more mass • The floating balloon has less mass • The masses of the floating balloon and the uninflated balloon are the same. Explain your answer

  2. Section 3.3 The Behavior of Gases The sum of all the “pushes”of all the particles in sample of matter on their container. Pressure = Force/Area A measure of the average speed of particles in a sample of matter The amount of space a sample of matter occupies barometer Liquids – Graduated Cylinder Solids & Gases – formulas thermometer

  3. Build a Barometer • Build a barometer with a beaker, tap water, and a graduated cylinder Atmospheric pressure is 14.7 pounds per square inch!
