Question

Match List - I with List - II.

Choose the correct answer from the options given below :

• A. A-IV, B-III, C-II, D-I
• B. A-III, B-II, C-IV, D-I
• C. A-I, B-II, C-III, D-IV
• D. A-IV, B-I, C-III, D-II

Hint:

Void ratio ($e$) can be greater than 1, but Porosity ($n$) is always expressed as a percentage between 0 and 100%. They are related by: $n = e / (1+e)$.

Answer 1

The Correct Option is D

Concept: Basic soil properties are expressed as ratios of volumes and weights of the three phases: solids, water, and air.

Step 1: Define the volumetric and weight ratios.

• Void Ratio (A): Ratio of the volume of voids to the volume of solids ($e = V_v / V_s$). Matches with IV.
• Porosity (B): Ratio of the volume of voids to the total volume of the soil mass ($n = V_v / V$). Matches with I.
• Degree of Saturation (C): Ratio of the volume of water to the volume of voids ($S = V_w / V_v$). Matches with III.
• Water Content (D): Ratio of the weight of water to the weight of solids ($w = W_w / W_s$). Matches with II.

Step 2: Final Matching.
The correct matching is A-IV, B-I, C-III, D-II.
