Thermodynamics and statistical physics form a cornerstone of modern physics, linking macroscopic phenomena to microscopic laws. While thermodynamics establishes broad principles—energy conservation, entropy increase, and equilibrium conditions—statistical physics supplies the microscopic rationale, explaining how the collective behavior of many particles gives rise to temperature, pressure, and phase transitions. Solved problems play a crucial role in learning these subjects: they translate formal theory into practical techniques, build physical intuition, and train students to choose approximations and calculational tools.

Problem: A paramagnetic solid consists of (N) non-interacting spins (S = \frac12) with magnetic moment (\mu). In a magnetic field (B) at temperature (T), compute the entropy, magnetization, and heat capacity. Resources and formats
Solution (summary):
Single-particle partition function: (z = e^\beta \mu B + e^-\beta \mu B = 2\cosh(\beta \mu B)).
(N)-particle: (Z = z^N).
Helmholtz free energy: (F = -kT \ln Z = -NkT \ln(2\cosh(\beta \mu B))).
Magnetization: (M = -\partial F/\partial B = N\mu \tanh(\beta \mu B)).
Entropy: (S = -\partial F/\partial T = Nk[\ln(2\cosh(x)) - x \tanh(x)]) where (x = \mu B/(kT)).
Heat capacity: (C_B = T \partial S/\partial T = Nk x^2 \textsech^2(x)).
(The PDF would then plot these functions and discuss the Schottky anomaly.)
