water evaporates anywhere that has some sunlight. its not really true that it has to be really hot for water to eveaprate.
Sunlight really doesn't have much to do with evaporation other then heat.
2 ways evaporation happens,
1. By absorption. This is one way evaporation can happen when things, like air and water, are contained in the same space (water out in a open container). Air actually absorbs the water molecules and the moisture content of air is referred to as humidity. Warmer dry air absorbs moisture fastest and cool "damp" air absorbs it slowest.
2. By boiling, this is the only way evaporation happens if there is only one fluid substance. for example, if you had water in a container and put a vacuum on it to 18000 microns (microns is a way to measure vacuum, 0 = a perfect vacuum = there is nothing in that space. 18143.7 = water boils at 69 Fahrenheit. 759,993.4 = atmospheric pressure = water boils at 212) if you had the water in a room that was warmer then 69 and a vacuum of 18000 microns the water would boil and evaporate, there would be no air in the container. Similarly if you have water on your stove at atmospheric pressure (normal air pressure) you would boil at 212, and the water temperature would stay at 212 until the water was all gone. That is evaporation by boiling and for water at 212 it takes 970 BTUs/lb

On what conditions does a spontaneous reaction become spontaneous?
For some non-spontaneous reactions, you can change the temperature. For other non-spontaneous reactions, there is nothing you can do to make it spontaneous. Nature favors reactions that increase a system's entropy (disorder) and nature favors reactions that are exothermic (they release enthalpy). Any reaction that does both of these things is spontaneous at all temperatures. Any reaction that does neither of these things is never spontaneous. As far as this question is concerned, the interesting reactions are endothermic reactions that increase entropy and exothermic reactions that decrease entropy. Whether these reactions are spontaneous depends on the temperature. The first variety (endothermic, increase entropy) will be spontaneous at high temperatures; the second (exothermic, decrease entropy) will be spontaneous at low temperatures. To find the temperature at which a reaction becomes spontaneous, one may apply the Gibbs equation: DG = DH - TDS where capital Ds stand for the Greek capital delta.
How would you write the equation to show water evaporation?
The equation for water evaporation can be represented as: H2O (liquid) → H2O (gas) This shows the process where liquid water turns into water vapor through evaporation.
How does the temperature affect how juice and water evaporate?
At higher temperature evaporation is faster.
What temperature does boiling water get to when it starts to evaporate?
Evaporation occur at any temperature.
What happens to the speed of evaporation when the temperature of water is higher?
The speed of evaporation increase when the temperatre increase.
Why is evaporation considered a spontaneous process?
Because even if you keep water in a plate in room temperature, ti evaporates on its own.
What is the evaporation range of water?
Water is evaporated at any temperature but a high temperature favors evaporation.
Does evaporation when water is warm or cool?
Water is evaporated at any temperature but a high temperature favors evaporation.
Does the rate of water evaporation increase or decrease as temperature rises?
As temperature rises, the rate of water evaporation increases.
Does evaporation need hot or cold water?
Evaporation occur at any temperature but a high temperature favors evaporation.
What is the effect of temperature on the effect of evaporation?
Rapid evaporation helps reduce the temperature of water.
What are 5 characteristics on evaporation?
Evaporation is a phase transition from liquid to gas that occurs at the surface of a liquid. It is a spontaneous process driven by an increase in temperature and the kinetic energy of molecules. Evaporation causes cooling of the remaining liquid due to the energy required to break intermolecular bonds. Factors influencing the rate of evaporation include temperature, surface area, humidity, and air movement. Evaporation plays a crucial role in the water cycle by redistributing water vapor in the atmosphere.
Does evaporation only happen when water is heated to high temperature?
Evaporation occur at any temperature.

How are the evaporation and condensation of water important to regional temperatures on earth?
Evaporation of water decrease the temperature.
Is air temperature or water temperature more important to evaporation?
Air Temperature, because the surface of the water is the only thing that needs to be heated so the warmer the air temperature, the faster the air can heat the surface of the water the faster evaporation will be able to occur,
What point does water have to reach to make evaporation?
Evaporation is possible at any temperature.
