A molecule within a sample of a liquid is attracted equally in all directions by other molecules, so there's no net force on the molecule in any direction. Water molecules on the surface are attracted by other molecules in the liquid, but by nothing outside the liquid. This gives surface molecules a net attraction toward the interior of the liquid. As a result, the surface area of a liquid tends to be very small. In a sphere, the surface area is minimized relative to the volume, which is maximized. That's why a drop of water is nearly spherical. To increase the surface area of a liquid, energy is needed to overcome the attractive forces that pull the molecules in toward the center. Surface tension is the energy needed to increase the surface area of a liquid by a given amount. Surface tension gives a liquid a skin. This skin allows very light objects to remain on the liquid's surface without penetrating it.求翻译~要求不是在翻译器上面翻译的~谢谢.对的加10分!
