Keep a chilled bottle from the fridge on normal room temperature, you will find some droplets of water on it. Give a reason for these droplets.

When a cold bottle is taken out from the refrigerator, the water vapour present in the room surrounding the bottle condenses and form droplets of water on the surface of the bottle.

This happens because the temperature of the room is warmer compared to the temperature inside. Thus water droplets form due to condensation.
