What mass of steam at 100∘C must be added to 1.80 kg of ice at 0∘C to yield liquid water at 20 ∘C? The heat of fusion for water is 333 kJ/kg , the specific heat is 4186 J/kg⋅C∘ , the heat of vaporization is 2260 kJ/kg .
Here we use the law of mixtures to find the mass of steam added
According to law of mixtures,
Heat lost by steam= Heat gain by ice
