The following gives the calorimetric values for water at various phases:


Latent heat of fusion for water: 3.33 E5 J/kg
Specific heat capacity for ice: 2,220 J/kg°C
Specific heat capacity for liquid water: 4,186 J/kg°C


A 15-g sample of ice at −20.0 °C is converted to liquid water at 15.0 °C. Using the values from the table above, calculate the heat required for that conversion.
4,500 J
6,600 J
7,800 J
9,500 J
