Does the size of a container opening affect how fast it evaporates?

Answer 1

Your question, despite the answers, does not give enough information.

Two examples.

Two bottles of equal size, each half full One is stoppered while the other is stoppered but has a small 1/8" hole drilled thru the stopper.
Result: The one with the hole will evaporate (obviously) since the bottle will never fill with evaporate from the fluid like the stoppered one does. This meets your criteria.

Example two..

Two bottles, each with the same amount of fluid One bottle necks down to a tiny throad while the other widens out as it increases in height. Result: The wider one will evaporate first as it has more surface area and more molecules can escape from that surface.

In both these cases, the wider the hole the faster it evaporate

Now picture the bottle with a very narrow throat above the liquid that flares to a wide one, (vs. one that does not flare)

The wider opening does not increase the evaporation since the neck of the bottome of the flare controls the rate of evaporate. Thus the opening may or may not affect the rate of evaporation..... sorry.

Answer 2

Water Evaporation is dependent upon: -
The temperature, the surface area presented to the escape of molecules, velocity of the wind, the humidity of the atmosphere.

Answer 3

Yes. Evaporation occurs when by chance a molecule in the liquid is moving fast enough to escape when it hits the surface. The greater the surface, the greater the chance that the molecule will be at the surface when it is moving fast enough to escape.

Answer 4

yes.

if you have the same amount of water in a tall thin container and a shallow wide container the liquid in the latter will evaporate first.

Answer 5

yup! its exposed surface area
