Video on microstates, macrostates and multiplicity. Example: two state model.
As you see you will need some of your knowledge in statistics. Some questions to recap:
1 How many ways are there to arrange the cards in 52-cards?
A) 52! B) 5252 C) 252 D) Some other number
2 You flip a coin 10 times. How many sequences (like HHTTHTHTTH) or microstates are possible?
A) 10! B) 102 C) 210 D) Some other number
3 You flip a coin 10 times. How many combinations are there with 2 heads and 8 tails? (Like TTTHTTTTHT )
A) 1024 B) 100 C) 90 D) 45 E) Some other number
4 You flip a coin 10 times. What is the probability that you will get 2 heads and 8 tails (in any order)?
A) 45/(210) B) 45/100 C) 45/10! D) 45/90 E) Some other number
Video on multiplicity of 3 models: 2-state paramagnet, random walk and Einstein crystal
5 Einstein solid with N = 3, q = 4. What is W(N = 3, q = 4)?
A) 43 B) 34 C) 3×4 = 12 D) 15 E) Some other number
Video on coupled Einstein crystals: Thermal equilibrium.
6 Two Einstein solids, A and B, are in thermal contact. The two solids are thermally isolated from the rest of the universe. NA? = NB = 10. qtot = qA + qB = 20. How many macrostates are there?
A) 10 B) 21 C) 2020 D) E) 20
7 Two Einstein solids, A and B, are in thermal contact. The two solids are thermally isolated from the rest of the universe. NA? = NB = 10. qtot = qA + qB = 20. Are all the microstates of solid A equally likely?
A) Yes B) No
