1. What are three things that distinguish fermions and bosons from each other? For each thing or characteristic you mention, explain what's true for fermions and what's true for bosons.
What are two examples of fermions and two examples of bosons?
Note: If you are interested, check out a very short quiz on fermions and bosons to see if you've "got the story!"

2. The average orbital occupancy f(e) for a gas at room temperature and atmospheric pressure is only about 10-6. What must be the approximate value of (e-m), expressed in units of t?
Do you get different answers to this question if the gas is composed of fermions and if it is composed of bosons? Why or why not?
3. Which of the following is true about the Fermi level and the Fermi energy?
Check the correct answer: a) The chemical potential m can also be called the Fermi energy.b) The value of the Fermi energy at t=0 is called the Fermi level.c) The value of the Fermi level at t=0 is called the Fermi energy.d) When the orbital energy e is equal to the chemical potential, the orbital is half-filled, for both fermions and bosons.
