The total entropy change is (with T in Kelvins) system 285.39 273.15 285.39 ln ln ln 293.15 263.15 273.15 273.15 ( 11.24 0.66 1.47 9.75)J/K 0.64 J/K.

In coming to equilibrium, the heat lost by the 100 cm 3 of liquid water (of mass m w = 100 g and specific heat capacity c w = 4190 J/kg K) is absorbed by the ice (of mass m i which melts and reaches T f > 0 ° C). We begin by finding the equilibrium temperature: () () warm water cools ice melts
