needed per group of 4 students:
2 empty small
plastic soft drink containers of the same size, 2 eight inch balloons,
hot plate and pan or beaker of boiling water, ring stand and clamp to
hold container in water.
Click on Animated Gas Lab.
On the left, under "Freeze One Variable," click on Mass.
After mass is frozen, click on Pressure so that it is also
frozen. Next, click on the green area "Effect of changing volume
on temperature." Answer the questions shown below:
variable is plotted on the graph's vertical axis?
variable is plotted on the graph's horizontal axis?

up two balloons to the same size, about 6 inches in diameter. Place
the opening of one balloon over the opening of each plastic bottle.
Make sure the air doesn't leak out and that both balloons still have
the same volume. Leave one bottle on the table and place the other in
the hot water bath. Use the clamp to hold the bottle in position, so
that it does not float. Describe what happens to the balloons.
18. How does
your experience with the balloons compare to the animated gas lab?
