58 Paheli asked for a glass of water from Boojho. He gave her a glass of ice-cold water. Paheli observed some water droplets on the outer surface of the glass and asked Boojho how these droplets of water were formed? Which of the following should be Boojhos answer?
Condensation of atmospheric water vapor
The explanation for the correct option:
(D)-Condensation
The process of conversion of water vapour into its liquid form is called condensation. Example: The morning dew on the grass.
When a glass of ice-cold water is placed at room temperature, droplets of water appear on the surface. When we retain ice-cold water in a glass, the temperature of the glass drops is lower than that of the surrounding environment. Water vapours can be found in the atmosphere. Water vapour from the atmosphere condenses on the glass's surface.
This is due to the fact that the temperature of the glass is substantially lower than the ambient temperature.
Water vapours condense into water droplets at lower temperatures.
As a result, the water droplets on the glass surface are the result of atmospheric water vapour condensation.
Evaporation
The process of conversion of water into its vapour or liquid into a gas is called evaporation.
Final answer: A correct answer is an option (D)
