If Hanson measured the mass of the soil beforehand and then Slowly pour water into the container and measure the volume of water that the soil absorbs. This would improve Hanson's Soil porosity experiment.
What is porosity of soil?
- The percentage of total soil volume taken up by pore space is known as soil porosity.
- The porosity of a soil is essential for a variety of reasons. The fact that soil pores contain the groundwater that many of us drink is one of the main reasons.
- The oxygen contained within these pore spaces is another significant feature of soil porosity.
- Because all plants require oxygen to breathe, a well-aerated soil is essential for agricultural production.
- Soil particle texture, soil structure, soil compaction, and the amount of organic material in the soil all influence its porosity.
- A fine-textured soil can hold more water than a coarse-textured soil.
How will measuring the mass of soil beforehand will improve Hanson's experiment?
- when the mass of soil is measured prior to the experiment, it will contain a certain mass (M1) which will be lesser than the one gained after the experiment.
- After water is poured over the soil, the mass (M2) of the soil will increase due to absorption of the volume of water.
- the total water absorbed can be calculated by subtracting M2 from M1 which will give the total volume of water absorbed by the soil.
other options are incorrect:
- if he measured the volume of the soil beforehand soil is measured in mass and liquids like water have a volume
- if he measured the porosity of the water beforehand, water does not have porosity
- if he measured the mass of the water beforehand, water does not have mass it has volume. measuring volume of water before experiment is of no use.
