Question

The levels of soil density are given below: (A) Saturated density
(B) Submerged density
(C) Wet density
(D) Dry density
Choose the most appropriate sequence in the decreasing order of magnitude of the densities of a soil sample:

• A. (C), (B), (A), (D)
• B. (A), (B), (C), (D)
• C. (A), (C), (B), (D)
• D. (A), (B), (C), (D)

Hint:

Wet density>Submerged density>Saturated density>Dry density.

Answer 1

The Correct Option is A

Step 1: Density Definitions.
- Wet density: Highest density, includes soil and water mass.
- Submerged density: Intermediate density, less than wet but more than saturated.
- Saturated density: Includes dry soil mass and water content.
- Dry density: Lowest density, considers only soil solids (no water).

Step 2: Density Order.
The correct order, from highest to lowest, is: Wet density (C), Submerged density (B), Saturated density (A), Dry density (D). Therefore, option (1) is correct.

Final Answer:
\[ \boxed{1. \, (C), (B), (A), (D)} \]
