  1. Nov 14, 2007 #1
    1. The problem statement, all variables and given/known data
    An 11 kg bowling ball at 0 degrees C is dropped into a tub containing a mixture of ice and water. A short time later, when a new equilibrium has been established, there are 5.0 g less ice.
    From what height was the ball dropped? Assume that no water or ice splashes out.

    2. Relevant equations

    3. The attempt at a solution
    I dont know what to do after this.

    You should find out how much energy it would take to melt 5 g of ice.

    Is there a formula to find how much energy it takes for 5g of ice to melt?

    You need to use the enthalpy of fusion. For water it is 6.0095 kJ/mol, or 333.55 kJ/kg
