comment Why can't I evaporate water without wind, just heat? (not boiling,evaporating!) Or can I?
LOL, loved the last sentence! First of all, evaporation doean't raise the surface to boling temp, right? So is there going to be some other process with the heating lamp? Second, you said it yourself, that wtaer vapour is lighter than air, so shouldn't it rise like in a hot air baloon? thx!

Mike dunlavey, thank you for your answer. Naturally if the tube is more narrow and less floor space is availiable the pressure increases. If the interconnected tubes are of different sizes then the pressure is equalibrilised until both tubes have the same height of water and the same pressure. In my original question I should have summed the weights up. 100 kg. (101kg technically). Thank you very much!!!!

Thank you guys for your help. Jcohen79, thank you, so you are saying that in an open container if we hang a heating lamp/coil above the water it would evaporate slower than if a wind carrying the same amount of energy hit the water. But why? If we have no vapor pressure outside?I'sn't the whole point of evaporation is surface molecules urging to break free and move with great speed and freedom out in the big world like a blonde girl from a small town arriving to Hollywood XD... (The wind from the evacuating molecules is no problem since it doesn't add any new heat to the water).
