Introduction
The pressure of a gas is influenced by its volume, number of particles, and temperature. When you push a tire pump handle down, you increase pressure by decreasing volume. You can increase the pressure in a bicycle tire by adding air particles. And, the pressure may become dangerously high inside an “empty” hair-spray can if it is heated. In this contest, you will use a clean, dry container and what you know about gases in an attempt to produce the highest pressure.
