Q. What is the stalagmometer used for?

Answer

A stalagmometer, a glass device for measuring surface tension, was commonly used to quantify alcohol content. Drops of a substance are counted and weighed, and the results are compared to those of water or some other standard liquid. Chemists and physicists use the device to determine the surface tension of a liquid. There are several names for stalagmometers. A liquid is supplied to a stalagmometer that is hanging vertically and allowed to flow out throughout an experiment. For the liquid to condense into a drop at the end, the tube must have a small base. The liquid will spill out of the tube once the volume of the drop reaches its maximum.
