Question

How much heat is required to convert solid ice with a mass of 985 g and at a temperature of -29.5 °c to liquid water at a temperature of 81.5 °c? (the specific heat of ice is cice = 2100 j/kgk, the specific heat of water is cwater = 4186.8 j/kgk, and the heat of fusion for water is: lf = 334 kj/kg.)?

Answer 1

Consider, please, this solution:

The final heat is:

Q=Q₁+Q₂+Q₃≈726.116 kJ
