# High Heat of Vaporization?

Heat of vaporization is the amount of heat absorbed when liquids convert into vapor. It also requires a certain temperature for conversion. The kinetic energy of the vapor is higher than the kinetic energy of liquid.

 Heat of vaporization is the heat energy needed to change liquid to a gas state. The units of energy a called "per mole". An example of this would be the amount of heat energy http://answers.ask.com/Science/Other/what_is_heat_...
 There are two reasons. One is that water molecules are able to form four hydrogen bonds each. This is a lot for a very small molecule. The more hydrogen bonds it has, the more energy http://wiki.answers.com/Q/Why_does_water_have_such...
 1. Divide the pressure at the first point by the pressure at the second point. In our example, it is P1/P2 = 0.66 atm / 0.55 atm = 1.2. 2. Calculate the natural logarithm of the value http://www.ehow.com/how_5394916_heat-vaporization....
