mesons don't melt
heat of fusion
414 kJ
Iodine sublimes - it does not melt
The unit for the heat of vaporization is J/g or Joules per gram of material. The amount of energy required = mass * heat of vaporization = 5.0 g * 5.0 J/g = 25.0 J (Q.E.D.)
The necessary heat is 9,22 joules.

heat of fusion
125.6 kJ (APEX)
No energy is gained. On the contrary, energy is required to make ice melt.
Energy is given off when cooling from a liquid to a solid. How much depends on the elements involved and the amount.
