We know that vapour pressure difference causes water to evaporate into the surrounding air stream.But there is something called molar concentration (kmol/m3).This molar concentration difference will cause diffusion of water vapour from higher concentration to lower concentration i.e from pool of water to air stream.
My question is "how can one single phenomenon have two different explanations"?(vapour pressure difference and molar concentration difference).
-for all mechanical and chemical engineers!!
These are the same explanations, as partial pressure has the same meaning, for gases, as a concentration. Only the units are different, but the same gradient of concentration (or partial pressure) is the driving force of the phenomenon.

Thank you Prof. Alain.
It means partial pressure/vapour pressure and molar concentration must be interconnected somehow.And there must be some mathematical relation between the two.i will try to find out that relation
Thank you very much!
Well both explain why humidity ratio is affected..the lower the humidity the faster the water evaporates into the surrounding environment...
