    So it's just the sign that changes . Thanks very much

    Thermodynamics phase changes steam and water

    Yes my physics book doesn't give those values though so I hadn't even thought I could use those.

    Thermodynamics phase changes steam and water

    So since the steam is undergoing a phase change to become water. I'm not sure what to multiply the mass for since it isn't fusion or vaporization.
