Answer the following statement(s) true (T) or false (F)
1. Consider the system where NA = NB = 1000, U = 5999? (see figure T2.6). Suppose that we can measure each object’s energy to within 0.01U ? 60? (the size of one bin). Once the system has reached a macropartition in the most probable bin, it will never spontaneously move to a macropartition outside that bin.
