Question

Hydrometer test is conducted for characterizing soil finer than

A. #4 sieve
B. #10 sieve
C. #100 sieve
D. #200 sieve

Answer 1

A hydrometer test is conducted for characterizing soil finer than the #200 sieve.

Step-by-step explanation:

A hydrometer test is conducted for characterizing soil finer than the #200 sieve. A hydrometer is an instrument used to measure the specific density of liquids. It consists of a sealed hollow glass tube with a wider bottom portion for buoyancy, a ballast for stability, and a narrow stem with graduations for measuring. By gently lowering the hydrometer into the liquid, the point at which the surface of the liquid touches the stem correlates to relative density.
