Ice To Water

  1. May 23, 2007 #1
    How much heat is required to change a 46.6 g ice cube from ice at -12.5°C to water at 53°C? (if necessary, use cice=2090 J/kg°C and csteam= 2010 J/kg°C)

    then i used Q=cmt and Q=mL


    then when i add all the numbers up i get 21792.723J total but the answer is wrong. i dont know if im using the formulas in the wrong order or what. ive done these problems in chemistry but its been a couple years since i took one of those courses. any help is appreciated.

    You use C_water, not C_steam for the last calculation (C_water is 4180)
