q1 = heat needed to raise T of water from 10 to 100.
q1 = mass x specific heat liquid water x (Tfinal-Tintial)
q2 = heat needed to vaporize the liquid water at 100 C to steam at 100 C.
q2 = mass water x heat vaporization.
q3 = heat needed to raise T of steam at 100 C to steam at 110 C.
q3 = mass steam x specific heat steam x (Tfinal-Tinitial)
Total Q = q1 + q2 + q3.
q1 = mass x specific heat liquid water x (Tfinal-Tintial)
q2 = heat needed to vaporize the liquid water at 100 C to steam at 100 C.
q2 = mass water x heat vaporization.
q3 = heat needed to raise T of steam at 100 C to steam at 110 C.
q3 = mass steam x specific heat steam x (Tfinal-Tinitial)
Total Q = q1 + q2 + q3.
