The enthalpy of fusion is the heat necessary to convert 1 kg of ice to liquid water. According to Wikipedia, this heat equals 333,55 kJ/kg.

Does this heat change with the temperature or pressure and if so, are there any correlations that model this dependence?

I am really looking for experimental measurements for different temperatures and pressures. It would be nice to have an expression for the latent heat in function of pressure, temperature.

  • $\begingroup$ Yes thank you for those links, but however they do not answer my question in case of fusion. $\endgroup$ – Pieter-Jan Weekx Apr 25 at 10:34
  • $\begingroup$ Are you asking for experimental measurements of the change in latent heat, or for theoretical approaches such as Kirchoff's law? $\endgroup$ – John Rennie Apr 25 at 11:40

  • $\begingroup$ It's no problem finding that information for latent heat of vaporization, since steam is so commonly used for engineering purposes. If I had my old textbooks with me, I would look through to see if any had it tabulated for fusion with the other water information. $\endgroup$ – JMac Apr 25 at 13:39
