Why does the rate of evaporation of an aqueous solution decreases with increase in humidity?
Wiki User
∙ 7y ago
As the humidity increases, the partial pressure of water vapor in the atmosphere (above the solution being evaporated) also increases. This results in more energy being necessary for the liquid water to evaporate, thus the higher the humidity, the longer it will take for evaporation of an aqueous solution to take place. This is essentially based on Dalton's Law of Partial Pressures.

Why does the rate of evaporation of an aqueous solution decrease with the increase in humidity?

Will the rate of evaporation of an aqueous solution decrease with increase in humidty?
Humidity is basically the amount of water vapour in the air. And evaporation is the vaporization of water into water vapour. So when the humidity is high there are already plenty of water molecules in the air so the water which gets vapourized into water vapour takes time to fill the gaps in the atmosphere and thus rate of evaporation is slow.
Why dissolving Ammonium nitrate(NH4NO3) in water is an endothermic although the temperature of the solution decreases?
The energy needed to support the endothermic reaction is supplied by the solution; thus the solution temperaturedecreases.If the reaction were exothermic, the solution temperature would increase.
Salt water can be separated by evaporation?
Yes. You can separate water from a salt solution by evaporation.
Why is a solution heated during evaporation in the laboratory?
Because evaporation is accelerated after increasing of the temperature.

Why the rate of evaporation of an aqueous solution decrease with increase in humidty?
At limes of low humidity fluids evaporate more quickly because they can be easily taken up by the surrounding environment, at 100% humidity evaporation stops, evaporated water can be measured as relative humidity

How does an increase in temperature affect the ability of a gas to go into solution?
it decreases solubility.... by damion /\
Does cold ringer's solution increase or decrease heart rate?
In decreases the heart rate.
How is concentration of hydronium ions affected when a solution of acid is diluted in water?
their is an increase in ion concentration
To increase the concentration of a solution?
In order to increase the concentration of a solution, you must add more solute or remove some solvent. You can remove solvent through evaporation.
Indicate whether the rate of dissolving increases or decreases for each of the following. a)heat the solution b)stir the solution c)grind the solution?
All these processes increase the rate of dissolution.
Should you use saline solution for contacts to clear your bearded dragons irritated eyes?
No, 100% no, if anything increase humidity slightly
Can evaporation make a saturated solution unsaturated?
No, evaporation will most likely make the solution supersaturated
Why does the percent ionization of acetic acid increase as the concentration of the solution decreases?
As you increase the concentration of the solution, the concentration of H+ does not change. Meaning, the concentration ionized does not change. Just the original concentration increases. Since percent ionization = (concentration ionized)/(original concentration) , and the original concentration is increased, the percent ionization therefore decreases.
Will the normality of an NaOH solution increase or decrease if the solution is exposed to air for prolonged periods?
If the solution volume remains unchanged, the normality will decrease as the NaOH will react with CO2 present in the air. Of course, if the solution volume is not held constant and if the evaporation rate is sufficient to concentrate the solution - it could also increase (effectively raising the normality of the remaining solution).
