WebWater has cohesive and adhesive properties. Water molecules have strong cohesive forces due to their ability to form hydrogen bonds with one another. Cohesive forces are responsible for surface tension, the tendency of a liquid’s surface to resist rupture when placed under tension or stress. WebSurface tension x Surface area = Surface energy. A falling drop of liquid assumes a spherical form because the ratio of surface area and total free surface energy is the least. 3. Method of Determination of Surface Tension: γ = 1/2 hdgr where, h = height of the liquid. ADVERTISEMENTS: d = density of the liquid, g = acceleration due to gravity,
