Would a swimming pool evaporate at 38 degrees over a long period of time?

Question

My friends says that for the whole pool to evaporate it would have to be more than 38 degrees [100 degrees]

I said that it will evaporate at 38 degrees just over a long period of time

Answers please

Answer 1

It will evaporate based on the humidity level of the air, the lower the humidity the faster it will evaporate. That is why ice cubes get smaller in your freezer.

Answer 2

Of course it will evaporate. It would eventually evaporate even if the air temperature was 1 degree Celsius, if it was dry enough.

Answer 3

Of course humidity and temperature are important factors in the evaporation rate, but wind is also a great contributor to increased evaportation.  Solar blankets prevent loss of heat in pools by reducing the surface area of water exposed to the moving air.  Think of a swimmer getting out of a warm pool on a windy day and reaching for a large towel to wrap themselves up, reducing the heat loss resulting from evaporation of water on the surface of their body.

On cool mornings you can see the effects of heat and moisture being removed from pools, ponds and lakes.

On freezing days with strong winds, you can also observe the sublimation of snow and ice.  

Wind also plays a great role in determining the levels of large bodies of water, like the Great Lakes.

Answer 4

Doc Bob has the right answer: water will evaporate if the air temperature is over the so-called dew point temperature, i.e. the temperature at which the air is 100% saturated and can't take any more. That happens when e.g. you're in a fog.

But otherwise, even below freezing point, water will evaporate. Here where I live, in Norway, people dry their clothes outside even it if is freezing. It may take a longer time but it will dry.
