A cube of ice is taken from the freezer at -5.5 degree C and placed in a 85-g aluminum calorimeter filled with 330 g of water at room temperature of 20.0 degree C. The final situation is observed to be all water at 16.0 degree C. The specific heat of ice is 2100 J/kg C degree, the specific heat of aluminum is 900 J/kg C degree, the specific heat of water is is 4186 J/kg. C degree, the heat of...
