Essential Concepts in Chemistry, Biology & Materials Science
Surface Tension Measurement Techniques
Surface tension, a critical property of liquids, can be accurately measured using several established methods:
Measurement Methods
- Du Noüy Ring Method: Measures the force required to pull a ring out of a liquid.
- Wilhelmy Plate Method: Measures the force exerted on a plate partially submerged in a liquid.
- Drop Weight Method: Measures the weight of drops falling from a capillary.
- Pendant Drop Method: Analyzes the shape of a pendant drop to determine surface tension.
