vaporizing water below 100° C

I'm little confused with the water being vaporized at atmospheric temperature to form clouds. Any explanation?

It's not just the temperate. Pressure above the surface plays role too. If the pressure above the surface is low the temperature required to boil water will be less. And vice-versa.

What of it's a closed vessel. Will water evaporate? I mean if you don't provide heat to system, then will there be any evaporation of water?

do you mean to say isolated system(not adiabatic)? When that happens, equilibrium is formed. The vapor will be formed which will create pressure on the surface of liquid which is called vapor pressure. This will resist the water molecules to evaporate further. If there is pressure of atmosphere from the beginning on the water, then water molecules will not evaporate. Hence pressure also plays an important role.
Hope this helps.  ::)
