what is meant by saying that the latent heat of fusion of ice is 3.34 x 105 J/Kg ??
For ice, the latent heat of fusion means that 334 kJ of heat is required to convert 1 kg of ice at 0ºC into 1 kg of water at 0ºC. Conversely, 334 kJ of heat is released when 1 kg of water freezes at 0ºC to give 1 kg of ice at 0ºC..
