q1 = heat required to change T from 25 C to 100 c.
q1 = mass H2O x specific heat water x delta T.
q2 = heat required to change liquid water at 100 C to steam at 100 C.
q2 = mass H2O x heat vaporization
total heat = q1 + q2.
q1 = mass H2O x specific heat water x delta T.
q2 = heat required to change liquid water at 100 C to steam at 100 C.
q2 = mass H2O x heat vaporization
total heat = q1 + q2.
