During the evaporation of liquid

Options

A. The temperature of liquid rises
B. The temperature of liquid falls
C. The temperature of liquid remains uneffected
D. The liquid molecules becomes inert

Answer

To solve the question regarding the change in temperature during the evaporation of a liquid, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding Evaporation**:
- Evaporation is the process where molecules at the surface of a liquid gain enough energy to overcome intermolecular forces and transition into the gas phase.

2. **Energy Consideration**:
- Molecules in a liquid have a range of kinetic energies. Some molecules have higher energy and can escape the liquid, while others have lower energy and remain.

3. **Kinetic Energy and Temperature**:
- Temperature is a measure of the average kinetic energy of the molecules in a substance. When molecules with higher kinetic energy evaporate, the average kinetic energy of the remaining molecules decreases.

4. **Effect on Temperature**:
- As the higher energy molecules leave the liquid, the average kinetic energy of the remaining molecules drops, leading to a decrease in temperature.

5. **Conclusion**:
- Therefore, during the evaporation of a liquid, the temperature of the liquid will fall.

### Final Answer:
The temperature of the liquid will fall (Option B).
