what factor does affect evaporation most?

Question

evaporation; its factors: windspeed, humidity, temperature

Answer 1

Humidity is the factor number one, followed by wind speed, and third is the temperature. Nevertheless, humidity and temperature are connected. The higher the temperature, the higher the amount of water that the air mass can hold without saturation. This principle is used for dehumidifier (they cool the air, water condensates and is collected, the air is warmed up and hence is dry.)

It is also very important the area or surface (of a lake) exposed to the atmosphere, the greater the surface, the greater the evaporation.

So maximum evaporation will occur in dry environments with high winds at high temperatures. Which is typical of most deserts.

The driest place on earth (hence, lots of evaporation) correspond to the Atacama desert in Chile, which is dry, windy, but not so hot. The evaporation is so high that if you leave bread uncovered for one or more minute, it gets stiff, like a toast. This places are great for producing dried fruits like raisins, etc.

Answer 2

All these affect evaporation.
but mostly temperature.

as the temperature rises, this adds more energy allowing the water molecules to become more excited, allowing more molecules to occupy the same space.

Example: basically how a steam engine works

try this
get 2 cups of water, one cool water, and another very hot water.
see how much sugar you can dissolve in cold and hot water.

the hot water will dissolve more sugar than cold.
but wait, until the hot water cools, the sugar will come out of the solution, as the sugar is now supersaturated. Same applies to humidity as the temperature falls the air cannot hold as much moisture

Answer 3

Hence, under standard conditions, only 970.4 Btu's would be required, and the ratio 1167.9 to 970.4 is the ratio determining the factor of evaporation. ...

Answer 4

Humidity because if it's too humid, the air cannot hold more moisture?

Answer 5

Make a little search on google and Yahoo!

Answer 6

i would say heat
