• volume of a gas = volume of a container

• The pressure of the gas is the force of its outward push divided by the area of the walls of the container

  • Pressure = Force/area

Boyles law:

• When the pressure of a gas at constant temperature is increased, the volume of the gas decreases. When the pressure is decreased, the volume increases.

• Temperature ↑ = Pressure ↑

• pressure ↓ = volume ↑

  Hint: Boyles law is best of all because it presses gasses awfully small

Charles law:

• When the temperature of a gas at a constant pressure is increased, its volume increases. When the temperature of a gas at a constant pressure is decreased, its volume decreases .

• temperature ↑ = volume ↑

  Hint: Charles watches TV
