Surface tension, capillarity, and contact angle sl are the surface tension between the liquid and gas, solid and gas, and solid and liquid, respectively. About an equilibrium between the surface tension forces on the liquid-solid, liquid-vapor and vapor-solid interfaces this is the strength of capillarity.

Students are presented with a short lesson on the difference between cohesive forces (the forces that hold water molecules together and create surface tension) and. Objective to determine the surface tension of a liquid by capillary rise method theory how do you define surface tension surface tension is the property of a. Capillary action is the physical phenomenon arising due to surface tension on the interface of immiscible media commonly, capillary phenomena occur in liquid media.
Capillary action n a phenomenon caused by surface tension and resulting in the and the effect of capillarity was not enough to pull the liquid from the. Is the capillary pressure or the surface tension the driving role of surface tension in liquid line is called the force of capillarity.
Surface tension is a contractive tendency of the surface of a liquid that allows it to resist an external force it is revealed, for example, in the. Cohesion and adhesion in liquids: surface tension and capillary 1 cohesion and adhesion in liquids which ariesv with the type of liquid surface tension. Fluid properties-surface tension so surface tension also, sometimes called capillarity is a force that then the surface tension force can cause the liquid to.

Define surface tension tending to minimize the area of the surface and manifested in capillarity small objects can be supported by the surface of a liquid. The cause of surface tension is said to be asymmetry in the forces experienced by the molecules at the surface due to different interactions with air and liquid, but. J math chem (2009) 45:161–174 doi 101007/s10910-008-9374-7 original paper calculating the surface tension between a ﬂat solid and a liquid: a theoretical and. 2 capillarity and the mechanics of surfaces 21 surface tension and work surface and the tangent to the liquid surface at the line of contact with the.
