One ice cube at -10oC weighing 30 g is added to a glass containing 200 g of water at 20oC. During the ice melting, additional 3.0 kJ of the heat are transferred from the glass wall to the ice-water mixture. The latent heat of fusion of the ice is 334 kJ/kg, the specific heat of the ice is 1.93 kJ/kg oC; and the specific heat of the water is 4.18 kJ/kg oC. Calculate the final water temperature when the ice cube melts completely.

A particular stage of an experiment requires a small sample of ice weighing 30 g to be brought from 273 K to 300 K in as short a time as possible, melting as it passes 273.15 K. If the specific heat capacities of ice and water are constant, with cpice =2.108 kJ/kgK and cpwater = 4.187 kJ/kgK, and the latent heat of fusion for ice is 334 kJ/kg, how much energy is needed to bring the sample to 300 K?
