The meaning of VAN DER WAALS FORCES is the relatively weak attractive forces that act on neutral atoms and molecules and that arise because of the electric polarization induced in each of the particles by the presence of other particles.
Van der Waals forces are essential in Gecko. Gecko uses van der Waals forces to stick on surfaces and climb walls. They have setae on the pads of their feet, allowing them to climb extremely smooth surfaces like glass. This force comes from fluctuations in charge distributions between neighbori...
3.1London–van der Waals Force Thevan der Waals forceis made up of three components; two of these are zero frequency dipole andinduced dipoleinteractions, which make very little contribution to the interaction in colloidal systems. The third force is the London ordispersion force, which is a q...
Van der Waals forces are the sum of the attractive and repulsive electrical forces between atoms and molecules. These forces differ from covalent and ionic chemical bonding because they result from fluctuations in charge density of particles. Examples of van der Waals forces includehydrogen bonding,di...

van der Waals force Also found in:Dictionary,Thesaurus,Medical,Wikipedia. [′van dər ‚wȯlz ‚fȯrs] (physical chemistry) An attractive force between two atoms or nonpolar molecules, which arises because a fluctuating dipole moment in one molecule induces a dipole moment in the other...
1)van der Waals force范德华力 1.In this paper,the torsional buckling of a multi-wall carbon nanotube embedded in elastic medium is investigated by considering the effects of the surrounding elastic medium and thevan der Waals force.研究了弹性介质中多壁碳纳米管的扭转屈曲,同时考虑了周边弹性介质...
Various van der Waals forces are dispersion forces, dipole-dipole forces and dipole-induced dipole forces.Q.2. Are hydrogen bonds a type of van der Waals Force?Ans: A hydrogen bond is a special type of dipole-dipole force. So it is considered a van der Waals force. A hydrogen bond is...
The adiabatic processes of ideal gas and van der Waals gas are discussed. 讨论了理想气体和范德瓦耳斯气体的绝热过程,着重指出理想气体的摩尔热容比只在高温段可看作常量,而范德瓦耳斯气体的摩尔热容比即使在高温段也不可看作常量。 更多例句>> 5
