Witryna14 sie 2024 · Surface tension is the energy required to increase the surface area of a liquid by a unit amount and varies greatly from liquid to liquid based on the nature of the intermolecular forces, e.g., water with hydrogen bonds has a surface tension of 7.29 … http://butane.chem.uiuc.edu/cyerkes/Chem102AEFa07/Lecture_Notes_102/Lecture%2024-102.htm
WitrynaThis works to reduce the surface area, attempting to create the shape with the minimal surface area, a sphere. The surface tension is the amount of energy required to … WitrynaSurface tension - resistance to distortion at the surface of the liquid from poking; The core principle is that the stronger the IMFs in the sample of molecules, the more strongly they interact, which means they stick together more. That leads to the following trends: Stronger IMF #-># Higher melting and boiling points (harder to melt and boil)
