Question

Which of the following processes is responsible for water getting cooled inside a clay pot?

• A. Diffusion
• B. Transpiration
• C. Evaporation
• D. Respiration

Answer 1

The correct option is C

Evaporation

The explanation for the correct option:

Option (C)

• Evaporation is the process by which water is converted to water vapour at room temperature.
• The water inside the pot will seep through the small pores of the earthen pot and evaporates from the surface.
• The latent heat for this state conversion is taken from the water inside the pot.
• As a result the temperature of the water inside the pot will come down and the water inside is cooled.

The explanation for the incorrect options:

Option (A)

• Diffusion is the process of movement of particles of a substance from an area of higher concentration to an area of lower concentration.
• The water in the pot has the same concentration. So diffusion will not occur.

Option (B)

• Plants lose water through the stomatal pores on leaves as vapor by the process of transpiration.
• The process occurs only in plants.

Option (D)

• It is the breathing process in which oxygen is taken in and carbon dioxide is given out.

Thus, Option (C) is the correct option.
