 The Kinetic Molecular Theory of Gases begins with five postulates that describe the behavior of molecules in a gas. These postulates are based upon some simple, basic scientific notions, but they also involve some assumptions that simplify the calculations. In reading a postulate, do two things. First, try to understand and appreciate the basic physical idea embodied in the postulate; this idea will ultimately be important in understanding the macroscopic properties of the gas in terms of the behavior the microscopic molecules making up the gas. Second, identify possible weakness or flaws in the postulates. Inaccurate predictions by a theory derive from flawed postulates used in the derivation of the theory. **[] **

**The Kinetic Molecular Theory explains how gases act. It describes its volume, motion, and temperature. It was found in 1857 by Rudolf Clausius. It includes solids, liquids, and gases.**

Samantha K  1. The popping of popcorn is an example of kinetic molecular theory. The kernels represent the molecules and the butter is the bonding forces between them. []  2. According to the Kinetic Molecular Theory, particles are in constant motion. If said particles are heated, they will move faster. A real life example of this is boiling water. As the water is heated, the particles begin to move much faster causing it to boil. []

 1. Identify the areas of high and low pressure and temperature.  2. Explain how pressure and temperature work together to produce the results shown in the video.  3. What gas law is demonstrated in the video?  4. The volume of a balloon is measure to be 3.25 liters at 1.25 atm and 25 ℃. What volume would the balloon occupy if the pressure is decreased to 0.95 atm and the temperature is increased to 40 ℃?

Adam L 1.higher pressure-in the atmosphere lower pressure-in the can higher temperature-in the atmosphere lower temperature-in the can 2.the temperature in the can gets decreased when it is dunked into the ice water which decreases the pressure in the can making it crumble since the volume is held constant. 3.gay-lussac 4.final volume=4.49 liters
