Surface tension arises from the cohesive force between the surface molecules. Interplay between cohesion and adhesion force make the surface inclined at acute or obtuse angle with the contacting solid surfaces. This causes a capillary rise (or fail) given as `h=(2Tcostheta)/(rhogr)`, where `theta=` angle of contact `T=` surface tension `rho=` density of the liquid, `g=` acceleration due to gravity and `r=` radius of the capillary tube.

Surface tension arises from the cohesive force between the surface molecules. Interplay between cohesion and adhesion force make the surface inclined at acute or obtuse angle with the contacting solid surfaces. This causes a capillary rise (or fail) given as h=(2Tcostheta)/(rhogr) , where theta= angle of contact T= surface tension rho= density of the liquid, g= acceleration due to gravity and r= radius of the capillary tube. In capillary rise:

Surface tension arises from the cohesive force between the surface molecules, Interplay between cohesion and adhension forces make the surface inclined at acute or obtuse angle with the contacting solid surfaces. This causes a capillary rise (or fall) given as, h=(2T cos theta)/( rho g r) where theta = angle of contact, T = surface tension, rho =density of the liquid, g = acceleration due to gravity and r = radius of the capillary tube.

Surface tension arises from the cohesive force between the surface molecules, Interplay between cohesion and adhension forces make the surface inclined at acute or obtuse angle with the contacting solid surfaces.

The potential energy of the liquid of surface tension T and density rho that rises into the capillary tube is

Explain the terms cohesion force, Adhesive force, surface tension force.

Given as : h=(2 S cos theta)/(r rhog) where S is the surface tension of liquid, r is the radius of capillary tube. rho is the density and g is acceleration due to gravity then dimensional formula for S is:

The cohesive force between the molecules of liquid is more than the cohesive force between the molecules of plate then angle of contact obtain is …..(acute /obtuse) and free surface has shape ….. (concave/convex)

The cohesive force between the molecules of liquid is less than the cohesive force between the molecules of plate then angle of contact obtain is …. (acute /obtuse) and free surface has shape ….(concave/convex)
