Homework Help: Thermodynamics Question

  1. Nov 15, 2009 #1
    0.50kg of ice at 0degrees is mixed with 0.1kg of steam at 100degrees. what is the final temperature?

    3. The attempt at a solution

    0.5*2100*(X-0) = 0.1*2000*(100-X)
    1050X = 20,000-200X
    3050X = 20,000
    X = 16

    But that's not the temp?

    Can someone please help me out. Thank you. Sirsh

    When the ice and steam are mixed, the ice will start melting and the steam will start condensing. You need to take into account the specific heats of fusion and vaporization.
