57 During summer, Boojho carries water in a transparent plastic bottle to his school. One day he left his bottle in the school. The bottle still had some water left in it. The following day, he observed some water droplets on the inner surface of the empty portion of the bottle. These droplets of water were formed due to
evaporation and condensation
An explanation for the correct option:
(C) Evaporation and condensation
Evaporation
The process of conversion of water into its vapor or liquid into a gas is called evaporation.
Condensation
The process of conversion of water vapor into its liquid form is called condensation. Example: The morning dew on the grass.
The water in the plastic bottles heats up and evaporates throughout the summer. When the evaporated water collides with the bottle's cover, it condenses into water droplets. These water droplets subsequently gather on the bottle's empty portion.
The explanation for incorrect options:
Boiling
Boiling is an unnatural process in which a liquid is heated and evaporated as a result of continuous heating. Evaporation normally takes place on the surface of the heated liquid. Boiling normally occurs throughout the full mass of the heated liquid.
Saturation
Saturation solution: A solution in which no more soluble substance can be dissolved at room temperature or a given temperature.
Saturation is the point at which a solution of a substance can dissolve no more of that substance and an additional amount of heat substance will appear as a precipitate.
Final answer: The correct answer is an option (C)
