A glass of ice water was made by adding six 25 g ice cubes to one liter of water. If the water was initially 25C and the ice cubes were initially at -15C, what is the final temperature of the ice water?

  • Chemistry - ,

    heat absorbed moving ice from -15 to zero + heat absorbed by ice melting + heat absorbed by moving ice from zero to final T - heat lost by 1L water initially at 25 C = 0.

    [mass ice x specific heat ice x (Tfinal-Tinitial)] + [mass ice x heat fusion] + [mass melted ice x specific heat water x (Tfinal-Tinitial)] + [mass water x specific heat water x (Tfinal-Tinitial)] = 0
    Solve for Tfinal.
