3. How can you tell that air pressure inside the can is lower after the can cools?

Review

1. State Amontons’ law.


2. Assume you have a sealed jug that contains only air. If you heat the air in the jug, it will have a higher
   temperature. What other property of the air will also change?


3. A father does a classic experiment for his son, which is pictured in theFigure2.50. First, he put a small piece
   of paper in a glass bottle and lit the paper with a match. He immediately placed a shelled, hard-boiled egg
   over the bottle opening. The paper soon burned out, and after a few seconds, the egg slipped inside the bottle.
   Apply Amontons’ law to explain why.
