Does anyone know how much heat do I need to convert 95g. of ice at -25 C. to water at 30 C. the heat capacity of H2O(s) is 2.1 J/g*C.

  • 10th geade Chem -

    q1 = heat to move ice at -25C to zero C.
    q1 = mass ice x specific heat ice x (25)

    q2 = heat to melt ice at zero C to liquid water at zero C.
    q2 = mass ice x heat fusion.

    q3 = heat to move liquid water at zero C to 30C.
    q3 = mass water x specific heat water x (Tfinal-Tinitial)
    Total heat = q1 + q2 + q3.
