1.	It becomes easier to read the bottom part of the meniscus when the hydrometer is in a soil suspension.(a) True(b) FalseThe question was posed to me in final exam.The question is from Grain Size and Shape topic in chapter Molding and Core Sands of Casting-Forming-Welding I
Answer» The correct choice is (B) False For EXPLANATION: It is impossible to read the BOTTOM part of the meniscus when the hydrometer is in a soil suspension. In the hydrometer test, it is very necessary or essential to form a graph or table that gives a COMPOSITE CORRECTION as a function of temperature for the present of dispersing agent in the hydrometer.
