How much heat is necessary to change a 52.0 g sample of water at 33 degrees celsius into steam at 110 degrees celsius?

Answer 1

q1 = heat to raise T H2O from 33 C to 100 C.
q1 = mass H2O x specific heat H2O x (Tfinal-Tinitial)

q2 = heat to vaporize H2O at 100 C to steam at 100 C.
q2 = mass H2O x heat vaporization.

q3 = heat to raise T of steam from 100 C to 110 C.
q3 = mass steam x specific heat steam x (Tfinal-Tinitial)

Total q = q1 + q2 + q3.
