How long does it take for water to evaporate?

Question

I have a science project to do, and I need t oknow how long it takes! Help please!

Answer 1

well it either takes about  a few minutes with a small puddle .really small puddle

Answer 2

It depends on much water and how hot is. If you want to test you question, place 3 milimeters of water in your sink with the plug thing down so the water can't get out. Then place a lamp over the water and wait till the next day. You water should be evaporated.

Answer 3

In the bowl, we could see that the water level kept getting lower and lower. The water seemed to disappear. That is just like what happens in rivers, streams, ponds, lakes and oceans each and everyday. Water is absorbed back into the air by the process of evaporation. Have you ever seen a lake or pond in the summer when we have had a long period of time with no rain? The level of water goes down and down.

Air of any given temperature can contain some amount of water vapor. Just how much water vapor it contains depends on the air temperature. (The higher the temperature, the more water vapor air can hold.) If the air does not contain all of the water vapor that it can potentially hold, then water will evaporate from whatever water sources are available until the air does contain as much as possible. At this point, the air is said to be saturated.

Another way to look at this is in terms of a concept known as vapor pressure. Each component of a mixture of gasses contributes some portion of the total pressure of this mixture. The portion of the pressure that is contributed by each component is called the vapor pressure. The proportion of the pressure that water vapor can contribute to the total pressure of the air varies with temperature. (This, again reflects the fact that the total amount of water vapor that the air can hold is temperature dependent.) If the vapor pressure of water in the air is less than the total possible for water vapor, then water will escape from the surfaces of various water sources in the area. As water is evaporating, some of it is also condensing. However, as long as the vapor pressure is below the total possible in the air, the rate at which the water evaporates will exceed the rate at which it condenses. However, as more water goes into the air, its vapor pressure will increase. As its vapor pressure increases, the rate of evaporation will decrease and the rate of condensation will increase. These changes in rates will continue until saturation occurs. At the point of saturation, the vapor pressure of the water vapor equals the total possible for that given temperature. So, the rate of evaporation will equal the rate of condensation. In other words, water will be condensing out of the air as fast as it is evaporating. So, evaporation will occur even at temperatures that are well below 100 degrees C.

Answer 4

The rate that water evaporates can indeed be calculated, but it depends on a few more things than you mention. The evaporation rate is influenced by

1) The temperature of the water at the air-water surface

2) The humidity of the air

3) The area of the air-water surface

4) The temperature of the air (more on this below)

In a real-world situation of evaporating water, none of these three quantities above remains constant because the process of evaporation itself changes them. Water evaporating takes quite a lot of heat away -- 540 calories per gram -- when it evaporates. That's enough to cool down 540 grams of water by a degree, or 50 grams of water a little more than ten degrees. If you are not very careful to replace the lost heat energy during the evaporation, the temperature will go down. And even then the temperature right at the surface will be lower than elsewhere in the water and it will depend on

5) water currents convecting heat and the ability to keep the temperature constant at 100 degrees F.

Answer 5

It depends on how strong the temperature is, for example if the temp. was 30 degrees, it will evaporate rather quickly

Answer 6

it depends i think at hotter temperatures it would evaporate, though.
