This often happens in the Rocky Mountains as dry and warm Chinook winds blow in from the Pacific in late winter and early spring. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor. After all, the large surface area of the oceans (over 70 percent of the Earth's surface is covered by the oceans) provides the opportunity for large-scale evaporation to occur. Sometimes the transfer is so one-sided for a molecule near the surface that it ends up with enough energy to 'escape'.
We said earlier that heat is removed from the environment during evaporation, leading to a net cooling; notice how cold your arm gets when a physician rubs it with alcohol before pulling out a syringe with that scary-looking needle attached. What are the factors that affect the Rate of Evaporation?
The primary mechanism for water to leave the lake is by evaporation, which can be quite high in a desertupwards of 1,300 - 1,600 millimeters per year. How does water change from liquid to gaseous from? Sublimation is a common way for snow to disappear quickly in arid climates. This does vary geographically, though. Trial 3, show More. On a global scale, the amount of water evaporating is about the same as the amount of water delivered to the Earth as precipitation. The water in the glass will be cooled by the evaporation until an equilibrium is reached where the air supplies the amount of heat removed by the evaporating water. Evaporation of the liquid depends on the strength of the intermolecular forces that are between liquid molecules. Nuclear Regulatory Commission, evaporation is the process by which water changes from a liquid to a gas or vapor. This process of water changing into vapor on heating is called evaporation.
