How do hot air balloons work? 

3. Background
Theory developed by James Clerk Maxwell and Ludwig Boltzmann
Theory assumed that
Size of gas particles are negligible compared to the distance between them
There are no attractive or repulsive forces between the particles
Particles are in constant rapid motion (colliding)

4. The Kinetic energy (energy of movement) is proportional to the temperature
All collisions are perfectly elastic
These theories can be related to both Boyles and Charles Law

5. The Ideal Gas Law
An ideal gas obeys all the assumptions of kinetic theory under all conditions of temperature and pressure READ SECTION 8.11 (PG ) AND DO QUESTIONS

6. The Equation of State for an Ideal Gas
Boyle’s Law
(PV=Constant)
Charles’s Law
(V proportional to T)
Ideal Gas Law
(PV = nRT)
Avogadro’s Law
(V proportional to n)
Constant = Gas Constant = R = 8.31 J K-1 mol-1
