Packet 11: Bonus 14
This scientist’s accomplishments include developing a “hard rod” model for the lyotropic phase transition in liquid crystals. For 10 points each:
[10m] Among other relationships, the Peltier and Seebeck effects are connected by a set of equations named for what scientist, sometimes referred to as the “fourth law of thermodynamics”?
ANSWER: Lars Onsager [or Onsager reciprocal relations]
[10e] Onsager used a transfer matrix method to solve the 2-D form of this model, which represents ferromagnetism with a lattice of up and down spins.
ANSWER: Ising model
[10h] Onsager also extended Debye–Hückel theory to agree with this empirical law, which states that the molar conductivity of a solution is proportional to the square root of electrolyte concentration.
ANSWER: Kohlrausch’s law
