SUMMARY
The calculation of heat absorbed in changing 2 kg of ice at -5°C to steam at 110.0°C involves multiple steps using specific heat capacities and phase change enthalpies. The specific heats are 2060 J/kg·K for ice, 4180 J/kg·K for water, and 2020 J/kg·K for steam. The heat of fusion is 3.34 x 10^5 J/kg, and the heat of vaporization is 2.26 x 10^6 J/kg. By applying these values systematically, one can determine the total heat absorbed during the transformation.
