1. Gas Laws

2. main gas laws Boyle’s Law Charles’ Law Gay-Lussac’s Law Avogadro’s Law
Gas Stoichiometry

3. Boyle’s Law

4. Boyle’s Law At constant temperature
The gas particle in the cylinder apply pressure on the balloon.
By colliding with container walls

5. Boyle’s Law
• The volume of the cylinder increases, so the gas particles in the cylinder have more space to move • Particles collide less often, with each other or with the walls of the container

6. Boyle’s Law …and thus the volume of the balloon increases!
As volume increases, pressure decreases

8. Charles’ Law

9. Charles’ Law At constant pressure
Gas particles move inside a balloon and collide with the sides, creating the volume of the balloon

10. Charles’ Law
As the temperature increases, the kinetic energy of the gas also increases.
The gas molecules collide with the sides more frequently and with greater force.

11. Charles’ Law …thus the volume of the balloon will also increase
As temperature increases, volume increases

13. Gay-Lussac’s Law
