The liquid limit of a fine-grained soil is the water content at which the soil changes from:
Correct answer: D. Plastic state to liquid state
- A. Solid state to semisolid state
- B. Semisolid state to plastic state
- C. Liquid state to gaseous state
- D. Plastic state to liquid state
Explanation
At the liquid limit, soil changes from a plastic consistency to a liquid consistency. The boundary between solid and semisolid states is the shrinkage limit, while the semisolid to plastic boundary is the plastic limit.

About Soil Mechanics and Foundations
Soil mechanics examines index properties, phase relationships, classification, permeability, seepage, compaction, consolidation, shear strength and earth pressure. Foundations apply these principles to bearing capacity, settlement and shallow or deep foundation selection, with clear distinction between compaction, which expels air, and consolidation, which expels water over time.
