Review

1. State Boyle’s law.


2. Explain why the pressure of a gas increases when its volume decreases.


3. Imagine blowing up a latex balloon. Assume that you tie the balloon to prevent air from escaping and then
   squeeze the balloon with one hand, so there is less space inside it. Then assume you use both hands (and
   maybe a friend’s hands) to squeeze the balloon so there is even less space inside. What do you think will
   happen to the balloon if you keep squeezing it to a smaller and smaller volume? Explain your prediction.
