An insulated beaker with negligible mass contains liquid water with a mass of 0.205 kg and a temperature of 83.9 C Part A How much ice at a temperature of -10.0 C must be dropped into the water so that the final temperature of the system will be 32.0 C? Take the specific heat of liquid water to be 4190 J/kg . K, the specific heat of ice to be 2100 J/kg - K, and the heat of fusion for water to be 3.34105 J/kg.
