q1 = heat to melt ice
q1 = mass ice x heat fusion.
q2 = heat to raise T of liquid water at zero C to 100 C.
q2 = mass water x specific heat water x (Tfinal-Tinitial)
q3 = heat to change liquid water at 100 C to gaseous water (steam) at 100 C.
q3 = mass water x heat vaporization.
Total Q = q1 + q2 + q3.
q1 = mass ice x heat fusion.
q2 = heat to raise T of liquid water at zero C to 100 C.
q2 = mass water x specific heat water x (Tfinal-Tinitial)
q3 = heat to change liquid water at 100 C to gaseous water (steam) at 100 C.
q3 = mass water x heat vaporization.
Total Q = q1 + q2 + q3.
