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 the volume. You can increase the pressure in a bicycle tire by adding air particles. If an empty container of hair-spray is heated, the pressure may become dangerously high inside. In this contest, you will use a clean, dry container and what you know about gases in an attempt to produce the highest pressure.
- Measure pressure.
- Apply your knowledge of gases.
- Have fun.
