    (4.184 J/(g·°C)) x (29.0 g) x (100.0 - 52.5)°C =

    5763.46 J to heat the water to its boiling point

    (2257 J/g) x (29.0 g) = 65453 J to vaporize the water

    (2.000 J/(g·°C)) x (29.0 g) x (238.2 - 100.0)°C =

    8015.6 J to heat the steam to 238.2°C

    5763.46 J + 65453 J + 8015.6 J = 79232.06 J = 79.2 kJ total
