Surface Tension Khan Academy. Surface tension is the attractive force in liquids that pulls surface molecules into the rest of the liquid minimizing the surface area. Water molecules at the surface at the water-air interface will form hydrogen bonds with their. Only water has an unusually high surface tension because of the relatively high attraction of water molecules to each other through a web of hydrogen bonds water has a higher surface tension. Test your knowledge on cohesion adhesion and surface tension of water.

This property results from the cohesive forces between molecules at the surface of a liquid and it causes the surface of a liquid to behave like a stretched rubber membrane.

Surface tension is the attractive force in liquids that pulls surface molecules into the rest of the liquid minimizing the surface area. Ctrl click Double click. Attractive forces between molecules of the same type are called cohesive forces. Surface tension is a contractive tendency of the surface of a liquid that allows it to resist an external force. Cohesive forces are responsible for surface tension a phenomenon that results in the tendency of a liquids surface to resist rupture when placed under tension or stress.
