The capillary rise of water in a soil generally increases when the soil particle size:
Correct answer: B. Decreases substantially
- A. Increases substantially
- B. Decreases substantially
- C. Remains constant
- D. Becomes uniformly graded only
Explanation
Capillary rise is greater in smaller pores, which are commonly associated with finer soil particles. Clay may therefore show considerable capillary rise, although its movement of water is slow.

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.
