Question

Take a cooled bottle of water from the refrigerator and keep it on a table. After some time you notice a puddle of water around it. Why?

Answer 1

A cold bottle of water is taken out from the refrigerator and kept on the table. The air contains water in the form of water vapours. When the water vapours present in the air come in contact with the cold surface of the water bottle, the vapor gets converted into tiny water droplets, which is seen as a puddle of water around the cold bottle of water. This happens due to the condensation of water vapours present in the air.
