Given,
Degree of saturation S = 1
water content w = 100%
void ratio e = wG/s
∴ e = 1G/1
∴ e = G.
Degree of saturation S = 1
water content w = 100%
void ratio e = wG/s
∴ e = 1G/1
∴ e = G.

Understanding Water Content and Void Ratio
In soil mechanics, understanding the relationship between water content and void ratio is essential, especially in saturated soils.
Water Content Definition
- Water content (w) is defined as the ratio of the mass of water to the mass of dry soil.
- A water content of 100% indicates that the mass of water equals the mass of dry soil.
Void Ratio Definition
- Void ratio (e) is the ratio of the volume of voids (spaces filled with water and air) to the volume of solids in the soil mass.
- It is calculated using the formula: e = Vv / Vs, where Vv is the volume of voids and Vs is the volume of solids.
Saturated Soil Condition
- In a fully saturated soil, the voids are completely filled with water.
- This means that the volume of voids (Vv) equals the volume of water in the soil.
Relationship Between Void Ratio and Specific Gravity
- Specific gravity (Gs) of soil solids is defined as the ratio of the density of soil solids to the density of water.
- When water content is 100%, the void ratio (e) becomes equal to the specific gravity (Gs) of the soil.
Conclusion
- Therefore, for fully saturated soil with a water content of 100%, the void ratio is equal to the specific gravity.
- This leads us to the correct answer: C) equal to specific gravity.
