A 30 g ice cube at 0 °C is put in an equal mass of 98 °C water in an insulated container, and allowed to melt. After a while the resulting mixture is at a final (uniform) temperature. How much heat energy does the ice require to completely melt at 0 °C? What is the uniform temperature of the resulting 'mixture'? Note: assume that the heat capacity of water and ice are independent of temperature, and are 4200 J/kgK and 2100 J/kgK, respectively. The heats of fusion and vapourization of water are 3.33x10° J/kg and 2.35×10° J/kg, respectively. How much heat energy does the ice require to completely melt at 0 °C? Answer = What is the resulting temperature of the total liquid (in °C)? Answer = "C
