1. What is the relationship between the temperature of a gas and its distribution of kinetic energies? Is it possible to have particles with kinetic energies many multiples of the most common value?
2. What is the relationship between the speed distribution of a gas and the mass of the particles? How does this help to explain the relative ease with which hydrogen escapes from its containers?
