General properties of liquids.1. surface tension Because the molecules of the liquid with a strong appeal. The movement of an individual molecule so it is under the influence of other nearby molecules. The Middle molecules obtained from other molecules that gravity is equal in all directions around all the way. The surface molecules section will receive the gravity from the molecules at the bottom and the sides only. The molecules at the surface is pulled inside. Make the surface area of the liquid decreases least loe. Can be seen from the water droplets on a smooth and clean surface is a sphere, which will have a surface area less than the water that is in a style unfolds? Of the failed attempt to organize itself, with the smallest surface area because there is no surface tension-molecules on the top, therefore less stable molecule in the Middle. To reduce the surface area equal to a reduction of number of molecules at the surface, making it more stable, liquid liquid, in some circumstances, it is necessary to increase the surface area, where the molecules in the liquid to be moved to the surface. In this molecule, they must overcome the gravity between those around Lake the gulls or said must work. Used to expand the surface area of the liquid surface tension unit, called 1 (Surface tension).
