Calculate the change in heat when 3.05g of water vapor (steam) at 100.0 degrees celsius condenses to liquid water and then cools to 18.50 degrees celsius.

  • Chemistry -

    q1 = heat released by steam at 100 C condensing to water at 100 C..
    q1 = mass steam x delta Hvap.

    q2 = heat released in cooling from 100 C to 18.5 C.
    q2 = mass water x specific heat water x (Tfinal-Tinitial).

    Total heat released
    qtotal = q1 + q2.
