Temperatura aerului dintr‑o cameră de volum V = 40 m3 este t1 = 25 °C. În cameră se aduce un vas de capacitate calorică C = 400 J/K, ce conține o masă de gheață m = 500 g, la temperatura t2 = –10 °C. Considerând sistemul izolat, căldura specifică a gheții cg = 2 100 J/kg·K, căldura specifică a aerului c = 1 006 J/kg·K, densitatea medie a aerului rho = 1,29 kg/m3, determină temperatura aerului din cameră la stabilirea echilibrului termic.
