Small city, BIG ammenities! That is Hidalgo, Texas. The City of Hidalgo is located on lands settled by Spanish -colonizer Jose de Escandon in 1749, as an adjunct to the new settlement of Reynosa, both part of colonial Spain until 1821. The desert settlement was mainly involved with cattle grazing for some 150 years.
When something changes phase from solid to liquid, or from liquid to gas, it takes energy to break the intermolecular interactions. These interactions between the water molecules are what make it solid. When you have ice, these interactions are strongest, which is why ice is hard.
The heat of vaporization is when the phase transition is between gas<-->liquid (for water this occurs at 100 C), while the heat of fusion is between liquid<-->solid (for water this occurs at 0 C). 3.) So now that we know information from the two steps above, we can solve for the enthalpy.
