  •  Phase change - ice to water? (1+ / 0-)

    I am late to this party, and hope the diary will be posted again, because it needs more attention. Could someone comment on the effect of phase change on temperature change, and if it is different if ice to liquid transition occurs when ice is on solid earth or floating in liquid? For instance, in a glass of water with ice cubes (and ideal mixing), incoming heat will result in ice melting, but the temperature will not rise until all the ice is melted. All of the applied heat will go into the phase change of ice at 0 deg C, to water at 0 deg C. Only when all the ice has made the phase change, will the temperature of the water start increasing. I have not done extensive reading, but have not seen this explained in articles about glacial melting.
    Thanks very much for this discussion.

    The plural of anecdote is not data.
