Assume that no heat is lost to the surroundings and that the container has negligible mass. The specific heat of liquid water is 4190 J/kg ∙ °C and of ice is 2050 J/kg · °C. For water the normal melting point is 0.00°C and the heat of fusion is 334 × 103 J/kg. The normal boiling point is 100°C and the heat of vaporization is 2.26 × 106 J/kg.
