How much heat energy, in kilojoules, is required to convert 53.0 g of ice at -18.C to water at 25.0 C ?

  • Chemistry -

    q1 = heat to raise T of solid ice from -18 to zero.
    q1 = mass ice x specific heat solid ice x (Tfinal-Tinitial) (Watch the sign in Tf-Ti)

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

    q3 = heat to raise T of melted ice from zero to 25C.
    q3 = mass water x specific heat liquid water x (Tfinal-Tinitial)
