Question

Explain the process why we get droplets of water on a cold bottle kept outside taken from fridge what do you called this process

Answer 1

We get droplets of water on a cold water bottle kept outside directly from the fridge because of the process of condensation.
When the surface of the cold bottle kept in the fridge, where the temperature is below room temperature, is directly exposed to room temperature,where their is moisture, the process of condensation takes place. Condensation is the process of water vapours converting into water.
This can be explained as : the cold bottle kept in the refrigerator develops cold water vapours on its surface as the temperature is very low. When this bottle is directly exposed to the external environment the temperature of the vapours fall down which causes vapours to convert into water i.e. condensation.
This can also be observed when it is raining. When because of the heat of the sun the water present on the surface of earth converts into water vapour it rises up as hot air is light. When these vapours reach a certain height the temperature falls thus converting them into water droplets by the process of condensation.

Answer 2

We get droplets of water on a cold bottle when it is taken from the fridge and kept outside. This is due to the moisture present in the air. When the moisture of the air strikes the cold  bottle i condensates due to the presence of coolness and this results in the formation of water on the water bottle. This process is quite similar to process of raining.

This process is known condensatiom.
