3) {15 points) A box contains 2 sections separated by a partition. The left section contains \"3 of tlte entire volume. Initially, there are 2 ideal gas molecules in tlte le section, and a vacuum in the remainder of the box. In the nal state, each molecule has an equal probability of hein g in tlte left third [L], the middle third (M), ortlte right third (R) of the box. Explain each of your answers below, as always. all Find tlte probability that both molecules will simultaneously be in L. b} By what factor does the number of microstates of the gas increase when the partition is removed? c) Determine the change in entropy of the system as a result of removing the partition.
