Detailed explanation-1: -Water is converted from its liquid form to steam when the heat of vaporization is reached.
Detailed explanation-2: -When the heat is raised (for instance, as water is boiled), the higher kinetic energy of the water molecules causes the hydrogen bonds to break completely and allows water molecules to escape into the air as gas.
Detailed explanation-3: -The five main properties of water are its high polarity, high specific heat, high heat of vaporization, low density as a solid, and attraction to other polar molecules.
Detailed explanation-4: -The very high heat of vaporization of water is mainly a result of Hydrogen bonding. A very high quantity of heat energy is needed for evaporation. This amount of heat is called heat of vaporization. When heat is absorbed, hydrogen bonds are broken and water molecules can move freely.
Detailed explanation-5: -Water easily evaporates at its boiling point (212° F, 100° C) but evaporates much more slowly at its freezing point because of the heat energy required to evaporate the water. The opposite of evaporation is condensation. Condensation is the process of water vapor turning back into liquid water.
