2. Consider subsystems A and B, which can exchange heat but not particles. The energy level spacing is NOT the same for both A and B. The energy levels of subsystem A are separated by an amount of energy E. The energy levels of subsystem B are separated by an amount of energy 48. Subsystem A has 7 particles and a total energy of 4 s. Subsystem B also has 7 particles and a total energy of 4 2. Determine the direction in which heat will flow and thus whether subsystem A or B has the higher initial temperature. You mustjustify your answer using the appropriate linedot pictures and calculation of multiplicity and entropy. For entropy, use k=1
