It's complicated and hard to explain, but I'll try my best.
Evaporation occurs when a liquid changes to a gas, but only on the surface of the liquid volume. The gas molecules transfer heat to the liquid molecules. An unequal distribution of heat causes some liquid molecules to become gas molecules. It is random and uneven. Energy from the sun also spawns evaporation. When evaporation does happen, the molecules that leave the liquid body takes a lot of heat with it, therefor the average temperature of the liquid decreases. Evaporation depends on heat, humidity, and air movement.

What is the difference between Drop wise condensation and film wise condensation?
heat transfer rate high
What is the difference between film and dropwise condensation?
The rate of heat transfer in dropwise condensation is more than film type condensation.
High heat transfer coefficient film-wise condensation or drop-wise?
In dropwise condensation about 5-8 times higher coefficient than filmwise.
Types of interactions between earth's hydrosphere and atmosphere?
Evaporation, heat transfer, matter transfer, and a lowering of condensation are the types of interactions between Earth's hydrosphere and atmosphere.
Why saturated steam is used in exchangers frequently rather then superheated?
The heat transfer coefficient of superheated steam is poor. Saturated steam has a better heat transfer coefficient, and also most of the heat transferred from steam occurs because of the condensation phase change.
What has the author Zhenhua Yu written?
Zhenhua Yu has written: 'Electrodynamically (EHD) enhanced condensation heat transfer in horizontal shell and tube condensers'
What is convective heat transfer?
Convection heat transfer is the transfer of heat by the movement of a fluid.
Difference between film and drop wise condenation?
Film condensation occurs when a continuous film of condensed liquid forms on a surface, while dropwise condensation occurs when individual droplets of condensed liquid form and coalesce on a surface. Dropwise condensation is more efficient than film condensation in terms of heat transfer, but it is more difficult to achieve and maintain in practice.
What process changes gas into a liquid?
Condensation.
Can you use a sentence with the word condensation in it?
When we heat the cabin in the winter, condensation forms on the windows.The processes of evaporation and condensation.
What are two examples of heat transfer?
Convection - heat transfer through liquids.Conduction - heat transfer through solids.Radiation - heat transfer through vacuum.
How can this heat be reused or recycled?
condensation
