What are the five or six major points to the kinetic molecular theory (KMT)?
Gas particles have “elastic collisions”, using the terms kinetic energy and potential energy
describe what happens when gas particles collide with each other or the container walls that
hold them.

the “iodine thermometer” on a cool, morning versus the hot, daytime
Try “Document-Based Questions” #’s 110-113 on p. 437 of your textbook.
Explain the various speeds of a gas as the temperature of that gas is increased. (Hint: Explain
the Maxwell-Boltzman distribution curves at various temperatures using the websites:

distributing in this manner, but using it as a gas?
Describe and explain the different behavior shown by ice and dry ice when both are set on a
lab desk.
Explain the following statement; when you blow up (inflate) a balloon it is difficult at first, but
becomes easier once the balloon is slightly inflated and then really difficult at the end.
Describe and explain the behavior shown by a balloon when it is moved from a warm store to
a cold car.
Describe and explain the behavior shown by an aerosol can when placed into a fire.
Explain the crushing can demo. (H2 and O2 Balloon)

is 29.75 inches of mercury and falling. What piece of scientific equipment did he use to get
this measurement and how does that piece of scientific equipment work?
