This solution goes through step-by-step calculations for the heat fusion of water to determine heat energy required. A diagram of time versus temperature is attached in a .jpg file.

Solution Preview

** Please see the attached file for the diagram **

mass (m) = 100 g
initial state = ice
initial temperature (Ti) = 0 degrees C
final temperature (Tf) = 100 degrees C
final state = steam

Heat of fusion of water (Lf)= 6.02 kJ/ mole = 6.02*10^3 J/mole
1 mole of water = 18 ...
