Final answer:
The requested soil properties are calculated using the mass, water content, and void ratio provided. The answers vary based on the actual values of variables E, F, C, and D. The properties include bulk density, dry density, the density of solids, porosity, and degree of saturation.
Step-by-step explanation:
The question asks to determine various properties of a soil sample including bulk density, dry density, density of the solids, porosity, and degree of saturation. The calculations for these properties are based on the given dimensions and mass of the soil, its water content (F%), and a provided void ratio (0.CD).
- Bulk Density (ρbulk) is given by the total mass of the soil sample divided by its volume. As the dimensions are 10cm x 10cm x 10cm, the volume is 1000 cm³.
- Dry Density (ρdry) accounts for the mass of the solids only, and is computed by subtracting the mass of the water (based on F%) from the total mass before dividing by the volume.
- Density of the Solids (ρsolids) is the mass of the soil particles divided by the volume they occupy, which is affected by the porosity and void ratio.
- Porosity (n) is a measure of the void space in the soil and is related to the void ratio (0.CD).
- Degree of Saturation (Sr) is the ratio of the volume of water to the volume of voids, and is calculated using the water content and porosity.
The correct answers may vary depending on the actual number values for E, F, C, and D. To determine the correct set of values for this particular soil sample, these variables must be substituted into the respective formulas for bulk density, dry density, porosity, and degree of saturation, which are not provided in the question.
