Q4. (20 marks) A 500 g hot tea is at a temperature 100°C. Some ice at -10°C is added to cool it. Neglect energy transfers with the environment. The heat of fusion of water is 333 kJ/kg and the specific heats of ice and water are 2220 J/kg.K and 4187 J/kg.K, respectively. a) How much ice should be added to cool it to 40°C? b) If a 40 g ice is added, what is the equilibrium temperature?
