Homework Help: Energy required to convert ice to steam ?

  1. Apr 19, 2012 #1
    1. The problem statement, all variables and given/known data

    Find the energy required to change ' X " mass of ice at -18 degrees celcius to steam at 100 degrees celcius.

    Latent heat of fusion : 336 000
    Lt heat of evaporaton : 2300000
    SHC water : 4200
    SHC ice : 2108

    2. Relevant equations

    Q=m x latent heat vaporisation/ fusion

    3. The attempt at a solution
    m X 2108x15 + m X 336000+ m X 4200 X 100 + m X 2300000 but I don't know where to go frm there :(
