Question

how can you relate the formation of water droplets on the outer surface of the bottle taken out of the refrigerator with formation of dew ​

Answer 1

Answer:

This is due to the condensation process which take place when the water vapours touches the water bottle

Explanation:in this type of process the water vapour is present in our environment touches the bottle and lose energy which they gain from heating they lose the energy and condensers why cooling of water vapours the water droplets are seen outside the water

Answer 2

Explanation:

The water vapor of the air depends upon the specific temperature.

Dew point: An unsaturated air at a certain temperature is taken and its temperature is decreased, a temperature is reached at which the air becomes saturated with vapor.

This temperature is called the dew point temperature.

Saturated with vapor: If the amount of air exceeds this limit, the excess

vapor converts into water droplets. When the air contains maximum possible water vapor, it is said to be saturated with vapor at that temperature.

Now, if we take a water bottle out of a refrigerator, we will observe tiny water droplets on it:

(i) This means, due to decrease in temperature, the air cools.

(ii) It becomes saturated with water vapor.

(iii) As a result, the excess water

vapor gets converted into tiny droplets.

(iv) The dew-point temperature is decided by the amount of vapor in the air.
