To treat a burn on your hand, you decide to place an ice cube on the burned skin. The mass of the ice cube is 12.9 g, and its initial temperature is -13.9 °C. The water resulting from the melted ice reaches the temperature of your skin, 30.2 °C. How much heat is absorbed by the ice cube and resulting water? Assume that all the water remains in your hand. Constants: Quantity per gram per mole Enthalpy of fusion 333.6 J/g 6010. J/mol Enthalpy of vaporization 2257 J/g 40660 J/mol Specific heat of solid H2O (ice) 2.087 J/(g·°C) * 37.60 J/(mol·°C) * Specific heat of liquid H2O (water) 4.184 J/(g·°C) * 75.37 J/(mol·°C) * Specific heat of gaseous H2O (steam) 2.000 J/(g·°C) * 36.03 J/(mol·°C) *
