q1 = energy to raise T from 55C to 100 C.
q1 = mass x specific heat x (Tfinal-Tinitial).
q2 = energy to vaporize all of the water.
q2 = mass x deltaHvap.
total heat = q1 + q2
q1 = mass x specific heat x (Tfinal-Tinitial).
q2 = energy to vaporize all of the water.
q2 = mass x deltaHvap.
total heat = q1 + q2
