Factors that Influencing the Surface Tension of a Liquid
The force with which the surface molecules are held simultaneously is called surface tension. Theoretical Definition: “If a straight line is considered on the surface…

What is Cohesive Force?
Cohesive force: We know a certain material consists of some molecules. The attractive force acting between molecules of the same materials is called cohesive force.…
What is Adhesive Force?
Adhesive Force: If a material is kept in touch with another material then there exists a mutual attractive force between the molecules of the two…
Demonstrate Surface Tension Effect
Surface tension effect can be easily demonstrated by an experiment given below- When a circular ring of metal wire is dipped inside a soap-liquid and…
Surface Tension
Surface Tension All liquids have a common property – liquid surface always tries to form smallest area by shrinking. The force in the liquid for…
Stokes Law
Stokes Law: “The force required to move a sphere through a given viscous fluid at a low uniform velocity is directly proportional to the velocity…
Why Viscosity is called Cohesiveness of Fluid?
Viscosity is sometimes called cohesiveness of fluid. Again someone calls viscosity the intrinsic friction of fluid. Because the nature at viscosity force is almost that…
Similarities between Friction and Viscosity
Similarities between Friction and Viscosity Friction is a tenure used to refer to forces that oppose the relative motion in general. The property of a…
Dissimilarities between Friction and Viscosity
Dissimilarities between Friction and Viscosity Friction is a tenure used to refer to forces that oppose relative motion in general. The property of a fluid…
Effect of Pressure on Viscosity
Effect of pressure on viscosity We see that there is an effect of pressure on the coefficient of viscosity of liquids if pressure increases; the…
