Document Summary

Phys 3400 physics & physical oceanography, memorial university of newfoundland fall 2007. Please answer all questions clearly in the booklets provided and show all your work. (n, q) = (q + n 1)! q! (n 1)! Na = 6. 022 1023 mol 1 e = 1. 602 10 19 c. 0 c 273 k du = t ds p dv + dn dg = sdt + v dp + dn. [16 marks] consider an einstein solid with q units of energy and n oscillators. Here, we will consider the high t limit, i. e. q >> n . (a) [5 marks] using stirling"s approximation, ln n ! F for the system tends to decrease. (d) [5 marks] at room temperature and atmospheric pressure, kyanite is the stable phase of aluminum silicate, al2sio5. At a higher t but still at ambient p , another form of the material, an- dalusite, becomes more stable.
