Is it possible for a cup of water to completely evaporate in a room with a constant temperature?

Question

maybe have a little explanation of why or why not
thanks

Answer 1

If the constant temperature is above 0 degrees celcius, it will. Unless the air in the room is at 100% relative humidity. Relative humidity is the amount of gaseous water that the air can carry without it condensing. It increases with temperature.
At temperatures above the freezing point, an amount of water molecules is always changing to the gaseous phase. If it's hotter, this will happen faster. Thas all

Answer 2

Of course.

It's not about a constant ambient temperature. The fact is that molecules are always moving, although the lower the temp, the slower they move. When a molecule of water reaches the surface, it doesn't stop moving. But it may move through the surface, which would be evaporation. Given enough time, any liquid will completely evaporate. I'm sure that there is a physics formula that can tell you how long it will take, given that constant temp, but I have no clue what that equation might be.

Answer 3

Yeah, piece of piss. When you hang clothes out to dry, chances are that more than a cupful of water evaporates. Even when the temperature is well below freezing, evaporation takes place. I've dried clothes outside in Antarctica in sub-zero temperatures. In the Dry Valleys, clothes dry quite rapidly because the humidity is so low. We had an open 44 gallon drum full of liquid waste and the water evaporated until only a saturated solution of salts was left. The ice on the lakes evaporates directly there, without melting first; it's too cold to melt most of the time. And the locations on the ice with the sharpest curvature, like the edges of cracks, evaporate fastest, so cracks in the lake ice develop rounded edges. If you left a cup of water out in the open on a freezing cold day, eventually all the ice in it would evaporate.

Answer 4

Sure. Try it out!

At the surface of the water, there is a contant change of water from liquid to gas and gas to liquid. At 100% humidity, the rate of liquid → gas is equal to gas → liquid. At a lower humdity, more liquid will turn to gas than gas into liquid. The warmer it gets (at the same humidity), the higher the rate of liquid to gas, which make it evaporate faster. Depending on how large your surface area is, a cup of water may evaporate in a week or so.

Answer 5

First, one must make two assumptions.

Assume the volume of air in the room is not saturated with water vapor.

Assume the ambient temperature to be greater than zero degrees C.

Then the answer is yes.

If either of the above assumptions are false the answer is no.

Answer 6

yes it wold even though it is going to be a slow procces, it always going to evaporate, unlees the temperature is below zero

Answer 7

absolutely
the warmer the faster it will
if freezing or below, no

Answer 8

yes
