Question

1. Rate of evaporation of an aqueous solution decreases with increase in humidity

Answer 1

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. (It's like filling intermolecular space, only here the space isn't between molecules.)


Hope it helps...

Answer 2

Hi friend,

Humdity is the amount of vapour or moisture content prsent in atmosphere

if humidity is high...evaporation will be less as humidity is there...there will be no cooling

hope it hlps
