Q: What does stalagmometer used to measure?
  • A. Dynamic viscosity
  • B. Surface tension
  • C. Refractive index
  • D. Lighted activity
Correct Answer: Option B - A stalagmometer is a device used for measuring surface tension using the stalagmometric method. It is also called a stactometer or stalagmometer. The device is a capillary glass tube whose middle section is widened. The volume of a drop can be predetermined by the design of the stalagmometer.
