Question
A 26.0 g sample of ice at -17.0°C is mixed with 124.0 g of water at 81.0°C. What is the equilibrium temperature?ºC.

heat gained by ice moving from -17 to zero + heat gained by ice melting |+ heat lost by warm water + heat gained by cool water = 0
[mass ice x specific heat solid ice x (Tfinal-Tinitial) + (mass ice x heat fusion at zero C) + [masswarm H2O x specific heat H2O x (Tfinal-Tintial)] |mass cool H2O x specific heat H2O x (Tfinal-Tinitial)] = 0
Solve for Tfinal.
[mass ice x specific heat solid ice x (Tfinal-Tinitial) + (mass ice x heat fusion at zero C) + [masswarm H2O x specific heat H2O x (Tfinal-Tintial)] |mass cool H2O x specific heat H2O x (Tfinal-Tinitial)] = 0
Solve for Tfinal.
