Transport of Water in Plants
It describes the mechanism of ascent of sap by the theories of root pressure and transpirational pull. It explains the cohesion-tension-transpiration pull model of water transport.

7 Science Tricks with Surface Tension
Surface tension holds the surface molecules of liquids tightly together and makes for some fun experiments!
Professor Dave Explains
Viscosity, Cohesive and Adhesive Forces, Surface Tension, and Capillary Action
Liquids have some very interesting properties, by virtue of the intermolecular forces they make, both between molecules of the liquid and those between the liquid and some other material they are in contact with. Let's learn about...
