Water in earthen pot remains cool due to

Options

A. condensations
B. evaporation
C. sedimentation
D. sublimation

Answer

**Step-by-Step Solution:**

1. **Understanding the Earthen Pot**: An earthen pot is made from clay and has small pores that allow air and moisture to pass through.

2. **Evaporation Process**: When water is stored in the earthen pot, some of the water molecules at the surface gain enough energy to escape into the air as vapor. This process is known as evaporation.

3. **Cooling Effect**: As water evaporates, it takes away heat from the remaining water in the pot. This is because the molecules that escape are the ones with higher kinetic energy, which leaves the lower energy molecules behind. Consequently, the temperature of the water decreases, making it cooler.

4. **Conclusion**: Therefore, the reason why water in an earthen pot remains cool is due to the evaporation of water through the small pores of the pot.

5. **Final Answer**: The correct option is "due to evaporation."
