The specific of ice is 2.10 kJ/kg $^{\circ}$C,the heat of fusion for ice at 0$^{\circ}$C is 333.7 kJ/kg,the specific heat of water 4.186 kJ/kg $^{\circ}$C,and the heat of vaporization of water at 100$^{\circ}$C is 2,256 kJ/kg.What is the final equilibrium temperature when 10.0 grams of ice at -15$^{\circ}$C is mixed with 40.0 grams of water at 75$^{\circ}$C?

Question

Quizplus · Accepted Answer

The heat gained by the ice to reach 0°C, melt, and then warm to the final temperature must equal the heat lost by the water cooling to the final temperature. Calculating these values shows the final equilibrium temperature is 42.6°C.
