NEEDED ONLY TYPED SOLUTIONS

Question-1

a) Suppose you have four coins, all with tails up. You now rearrange them so two heads and two tails are up. What was the change in entropy of the coins?

(b) Suppose your system is the 100 coins of Table 20-1; what is the change in entropy of the coins if they are mixed randomly initially, 50 heads and 50 tails, and you arrange them so all 100 are heads?

TABLE 20-1 Probabilities of Various Macrostates for 100 Coin Tosses Macrostate Number of Heads Tails Microstates Probability 100 7.9 x 10 31 1.0 x 102 7.9 x 10 29 90 10 1.7 x 1013 1.4 x 10 17 5.4 x 1020 4.2 x 10 10 1.4 x 102 0.01 6.1 x 1028 0.05 50 50 1.0 x 1029 0.08 45 55 6.1 x 102 0.05 60 1.4 x 1028 0.01 80 5.4 X 1020 4.2 x 10-10 90 1.7 x 1013 1.4 x 10 17 1.0 x 10- 7.9 X 10 19 100 1 7.9 x 10 31
