A student performed an experiment to calculate the percentage of water absorbed by soil. He took 100 ML of water in a measuring cylinder and added a drop wise to 40 g of dry soil kept on the filter paper till the water started dripping from the soil in the funnel. He found that the water level fell down to 80 ML in the cylinder. Calculate the percentage of water absorbed.?

Experiment to Calculate Percentage of Water Absorbed by Soil
To calculate the percentage of water absorbed by soil, a student performed an experiment using the following steps:
1. Materials:
- 100 mL measuring cylinder
- Dry soil
- Filter paper
- Funnel
2. Procedure:
a. The student took 40 g of dry soil and placed it on the filter paper, which was set inside the funnel.
b. A 100 mL measuring cylinder was filled with water up to the brim.
c. The student added water dropwise to the soil kept on the filter paper until the water started dripping from the soil in the funnel.
d. The water level in the measuring cylinder was then recorded.
3. Observation:
- Before pouring water onto the soil, the measuring cylinder contained 100 mL of water.
- After the experiment, the water level fell down to 80 mL in the measuring cylinder.
4. Calculation:
To calculate the percentage of water absorbed by the soil, we need to find the difference between the initial and final water levels in the measuring cylinder.
Initial water level = 100 mL
Final water level = 80 mL
Water absorbed by soil = Initial water level - Final water level
= 100 mL - 80 mL
= 20 mL
Percentage of water absorbed = (Water absorbed / Initial water level) * 100
= (20 mL / 100 mL) * 100
= 20%
Conclusion:
The soil in the experiment absorbed 20 mL of water, which is equivalent to 20% of the initial water level. This indicates that the soil has a certain capacity to absorb water, and understanding this characteristic is important for various agricultural and environmental studies.
