In Method B, which device is used to soak the specimen in water?

• A. Volumeter
• B. Beaker
• C. Thermostatic bath
• D. Carousel mixer

Answer: (A)

Soaking the specimen in water during this method is done in a way that standardizes both immersion and the measurement of the specimen’s volume. A volumeter is the best choice because it is a calibrated vessel designed to hold the sample completely submerged and to measure the volume by water displacement. This setup ensures the specimen soaks under controlled conditions and that you can accurately determine its volume (and, if needed, changes in volume due to water absorption) as part of the test calculations. A beaker could be used to soak, but it isn’t calibrated to provide precise volume measurements or consistent submersion conditions, which are essential for repeatable results. A thermostatic bath controls temperature but isn’t the vessel that holds the specimen during soaking nor does it inherently provide volume measurement. A carousel mixer is meant for agitation, not for controlled soaking, and could introduce turbulence or inconsistent contact with water. So, the instrument chosen for Method B serves both immersion and volume-determination purposes, making the volumeter the appropriate device.
