1. How much heat energy is needed to transform 125g of ice at 0 degrees Celsius to warm water at 80 degrees Celsius?

  • Chemistry - ,

    q1 = heat to melt ice at zero C to liquid water at zero C.
    q1 = mass ice x heat fusion ice.

    q2 = heat to move liquid water from zero C to 80 C.
    q2 = mass water x specific heat water x (Tfinal-Tinitial)

    Total heat = Q = q1 + q2
