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
