Part A Calculate the enthalpy change, ΔH, for the process in which 42.4 g of water is converted from liquid at 15.3 ∘C to vapor at 25.0 ∘C . For water, ΔHvap = 44.0 kJ/mol at 25.0 ∘C and Cs = 4.18 J/(g⋅∘C) for H2O(l).

How many grams of ice at -16.2 ∘C can be completely converted to liquid at 25.5 ∘C if the available heat for this process is 4.77×103 kJ ?

For ice, use a specific heat of 2.01 J/(g⋅∘C) and ΔHfus=6.01kJ/mol .
