What is the required resistance of an immersion heater that will melt 6.39 kg of ice at 0°C in 36 min while operating at 110 V?

im not too sure how to do this because delta_T=0. With the equations im using, i get 0 but its not the answer and im not quite sure what to do.

thanks for the help in advance.

Energy required to melt ice at zero degrees C = mass times heat of fusion of water.
