q1 = heat needed to melt the ice at zero to form liquid water at zero.
q1 = mass ice x heat fusion = ?
q2 = heat needed to raise T of liquid H2O at zero to liquid water at 100 C.
q2 = mass H2O x specific heat H2O x (Tfinal-Tinitial)
q3 = heat needed to turn liquid water @ 100 C into steam at 100 C.
q3 = mass H2O x heat vaporization.
Total heat = q1 + q2 + q3.
q1 = mass ice x heat fusion = ?
q2 = heat needed to raise T of liquid H2O at zero to liquid water at 100 C.
