A two level system has energy levels E1 = 0J and 20 2 E =1.00×10? J . Suppose we distribute four particles marked as a, b, c, and d into these two energy levels. a) Calculate each of the four particle energy states of this system b) For each energy calculate the number of microstates W that have this energy. Make sketches of each of these microstates. c) Calculate the corresponding entropy for each state. d) Calculate the temperature for each state.
