Use what you learned from the PhET Simulation on the Properties of Gases and from the 3.04 Gas Laws lab to answer the following question. Write a paragraph!
Scenario (not a real experiment): Start with a balloon at room temperature, measure the diameter. Then put it into hot water and measure the diameter. Then put it into ice water and measure the diameter.
Explain why a balloon in hot water expands but a balloon in ice water shrinks. Be sure to include the following information:
(1) the number of molecules
(2) the temperature
(3) energy of the molecules
(4) the pressure
(5) the volume
