The boiling point of ethanol is 78 C but it can evaporate slowly at just room temperature. You can set it on fire and it will vaporize even more quickly.
heat is a mesure of energy the more energy the hotter it is so depending on its melting point is how much energy/heat is needed

The amount of energy needed to vaporize 175 g of water depends on the temperature of the water. However, we shall assume it is 100 degrees C. We multiply 175 by 539 and get 94,325 calories. (Notice the small c). We could express it as 94 Calories if we were talking about the stuff on your dining room table.

At standard pressure and temperature it takes about 6 Mj to vaporize one kg of iron. The high pressure at the core of the earth makes the central part solid and would probably increas the energy needed for vaporization.
