How many kilojoules are required to melt 15g of ice at 0 degrees C, and raise the temperature of the liquid that forms to 85 degrees C?

4 answers

q1 = heat needed to melt ice at 0C
q1 = mass ice x heat fusion = ?J

q2 = heat needed to raise T of liquid H2O from 0C to 85 C
q2 = mass H2O x specific heat H2O x (Tfinal-Tinitial) = ? J

Total q = q1 + q2 = ? in J.
Convert to kJ.
