N=∫0∞g(E)1eβ(E−μ)+1dEcap N equals integral from 0 to infinity of g of open paren cap E close paren the fraction with numerator 1 and denominator e raised to the beta open paren cap E minus mu close paren power plus 1 end-fraction d cap E is constant, pull it outside the integral:

): Since the particles are distinguishable and non-interacting:

𝜕⟨E⟩𝜕β=−Nϵ2eβϵ(eβϵ+1)2the fraction with numerator partial open angle bracket cap E close angle bracket and denominator partial beta end-fraction equals the fraction with numerator negative cap N epsilon squared e raised to the beta epsilon power and denominator open paren e raised to the beta epsilon power plus 1 close paren squared end-fraction Only after you've made a reasonable attempt should

Differentiating with respect to energy gives a constant density of states:

: Before peeking at the solution, give each problem a genuine and focused attempt. Use a notebook, write down all known quantities, state what you need to find, and try to map out a physical strategy. Which laws or ensembles are relevant? Only after you've made a reasonable attempt should you look at the solution to check your reasoning. : Covers the First Law, Second Law, entropy,

If you are searching for a "solved problems in thermodynamics and statistical physics pdf," look for these classic and reputable sources:

Many top-tier universities (MIT, ETH Zurich, Cambridge) offer course problem sets with solutions in PDF format. While not a single compiled book, a collection of 10–12 weekly problem sets effectively serves the same purpose. : Covers the First Law

: Covers the First Law, Second Law, entropy, thermodynamic functions, phase equilibrium, and nonequilibrium thermodynamics. Statistical Physics (Part II)
