Thermodynamics - again, Part of the ice that melt :S

  1. Jun 17, 2011 #1
    1. The problem statement, all variables and given/known data

    Stamp of iron the his mass - M and temp' - T0 (T0>100 C deg') has been placed on cube of ice.

    The mass of the ice - m, the temp' - t0 = 0 C deg'


    How many present of the ice get melt?

    2. Relevant equations

    Q = mc[itex]\Delta[/itex]t

    3. The attempt at a solution

    If I let all the ice getting melt, I got one equation with one unknown size - T (end)

    But if I define constant K that representative the presents of the ice that melt... I got two unknown sizes - K and T (end)

    What I supposed to do?!

    Thanks in advance!!

    Without actual numbers to put in the variables there are a number of different outcomes possible. Perhaps you are expected to identify and show formulas for all of the possibilities?
