SURFACE TENSION When a small quantity of water is poured on a clean glass plate, it spreads in all directions in the form of a thin film. If this interaction is much larger than the interac- 4rie com Conspiracy or Coincidence. This effect is calledcapillarity, and was observed in small tubes. The force per unit stretched length gives the measurement of surface tension.

This implies that, when soap is dissolved inwater, the soap molecules migrate to the surface: Since the interaction between soap molecules is weak, the surface tension If a body of weight W is placed on the liquid surface, whose surface tension is T.If F is the minimum force required to pull it away from the water then value of F for different bodies can be calculated by the following table. NOVA Official Website The Fabric of the Cosmos. surface tension module mit.
