10 kg of H2O is stored in an icebox at – 13.7 C. After a few days, the temperature is measured at 10.2 C. How much heat did the H2O gain? The whole system is at standard conditions, and assume that there was no material loss during those days.
The heat of fusion of H2O at its normal melting point is 334 J/g. Heat capacity in the liquid phase is 4.18 J/g/°C and in the solid phase is 2.1 J/g/°C. Melting point is 0 C.
Give your answer in kJ and with 1 decimal point.
