Answer:

Whenever we fill a bottle with cold water and place back the cap tightly closing it, why is it that after a few seconds we notice cold water droplets outside the bottle as if the water is coming out of the non porous plastic bottle? Also the same thing happens when the bottle contains hot water, so we can associate this with the thermodynamics' law of equilibrium, but then how and from where does this water form droplets outside the bottle? Because there can't be so much of moisture around in the air which is going to help in the droplet formation.

hope it's helpful for you mate

Gauravkarya: thankssssss
salonishrimali: Air contains moisture (water vapours) normally termed as 'humidity'. The warmer the air, the more water it can hold. Now when you pour in chilled water, the surface temperature of the bottle decreases and it becomes cold.
