Which of the following is unit of Viscosity?
Correct answer: C. Poise
- A. Decibell
- B. Torr
- C. Poise
- D. Hertz
Explanation
The poise is the CGS unit of dynamic viscosity, which measures a liquid's resistance to flow. Decibel measures sound intensity, torr measures pressure, and hertz measures frequency, so students may confuse other physical units with viscosity.

About Properties of Liquids
Liquid behavior depends on intermolecular forces, which produce surface tension, viscosity, capillary action and a definite volume without a fixed shape. The topic also covers vapor pressure, evaporation, boiling point and the effect of temperature and external pressure, while distinguishing evaporation at the surface from boiling throughout the liquid.
