Water in earthern pot remains cool due to

Options

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

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks why water in an earthen pot remains cool, especially during hot weather.

2. **Identifying the Options**: The options provided are:
- A) Condensation
- B) Evaporation
- C) Sedimentation
- D) Sublimation

3. **Analyzing the Properties of Earthen Pots**: Earthen pots are made of clay, which has many small pores. These pores allow water to seep through the pot.

4. **Understanding Evaporation**: When water evaporates, it changes from a liquid to a gas. This process requires energy, which is taken from the remaining water in the pot. As water molecules escape into the air, they take heat energy with them.

5. **Cooling Effect**: The loss of heat energy from the water due to evaporation causes the temperature of the remaining water to decrease, making it feel cooler.

6. **Eliminating Other Options**:
- **Condensation**: This is the process where vapor turns back into liquid, which does not cool the water.
- **Sedimentation**: This refers to the settling of particles and does not relate to the cooling of water.
- **Sublimation**: This is the transition from solid to gas, which is not applicable in this context.

7. **Conclusion**: The correct answer is B) Evaporation, as it is the process responsible for cooling the water in the earthen pot.

**Final Answer**: Water in an earthen pot remains cool due to **evaporation**.
