q1 = heat to melt ice.
q1 = mass ice x heat fusion.
q2 = heat to raise T of liquid H2O from zero C to 100 C.
q2 = mass H2O x specific heat H2O x (Tfinal-Tinitial)
q3 = heat to vaporize the water
q3 = mass water x heat vaporization.
Total Q = q1 + q2 + q3
q1 = mass ice x heat fusion.
q2 = heat to raise T of liquid H2O from zero C to 100 C.
q2 = mass H2O x specific heat H2O x (Tfinal-Tinitial)
q3 = heat to vaporize the water
q3 = mass water x heat vaporization.
Total Q = q1 + q2 + q3
