Unformatted text preview: common element in the Sun? 2. Assume a 1dimensional system where the energy, E, varies as E = E n 4 where n is the quantum number. At temperature, T , what is the mean energy of the system? 3. Consider a two level system with energy spacing E . Find the mean energy of the system as a function of temperature, T . What happens in the limits of high T and low T ? 4. Consider the MaxwellBoltzmann distribution. Compute the mean values of v x and v 2 x for a gas whose atoms have mass m . 5. Consider the MaxwellBoltzmann distribution for a gas with atoms of mass m and temperature T . Let n denote the number density of molecules. What is the mean rate (collisions m2 s1 at which the atoms collide with a at wall? 1...
