Question

Why does a cool water bottle taken out from refrigerator get water droplets on its surface.​

Answer 1

Answer:

Since water inside the bottle taken out from the refrigerator have lower temperature then the outside air in the atmosphere, due to this temperature difference air (with moisture in it ) get condense as it losses heat and thus water vapor present in the air form water droplets on the outer surface of the bottle

Answer 2

This is because first when we put the water bottle in refrigerator it's cool down and condensation process working there . Therefore , when we take out evaporation process started and it's started melting that's why water droplets seen on the surface
