warm oven, one in the freezer, and keep the other at room temperature.
f. You use a tape measure to measure how big each balloon is every 15 minutes for 5 hours.
You find that the balloon in the warm oven is expanding by about 5 centimeters per hour.
The balloon in room temperature is not expanding. The balloon in the freezer is shrinking by
2 centimeters per hour.
g. You conclude that air expands as it is heated, so that is why bicycle tires are flatter
winter than in summer.
