An orbital is an area of probability of an electron. . The electron does not have a uniform motion, at least we don’t think it does. We don’t know what the motion of an electron is. Liquids have molecules moving around in them. . Temperature is the average kinetic energy (which depends on the speed) of these molecules.. Some are moving. faster than others!. If they are moving fast enough, at just the right angle,. How is evaporation measured?. How is evaporation estimated?. Reading: Applied Hydrology Sections 3.5 and 3.6.

Physical Vapor Deposition (PVD) basically consist of vaporizing a source (target) in order for the transfer to and deposition on a substrate. “Net rate of vapor transport to the atmosphere”. Reverse process of precipitation. Evaporation considered to be a problem for reservoirs storage on one hand may prove very valuable on the other hand . Prof. . Dr. . Wisam. J. Aziz .
