As we all know that in atmospheric pressure (1 Bar) saturation temperature of water is 100 deg C. And the air contains mixture of dry air and water vapour.
My doubt is here that the water needs 100 deg Celsius to change from liquid to vapour state then how can a normal room temperature air contain water vapour. since it need 100 deg to start converting into vapour then how can water be in form of vapour at room temperature (say 20 deg).
One thing i also have doubt that how a water spread on floor gets evaporated at normal temperature. I know i am doing wrong anywhere but please clear the concept.
THANKS
