Explanation of Surface Tension by Laplace’s Molecular Theory

Explanation of Surface Tension by Laplace’s molecular theory of surface tension To explain the phenomenon of surface tension Laplace gave a molecular theory which is......

Molecular Range Definition

Molecular range: We know, cohesive force is inversely proportional to the square of distance between the molecules. As distance increases, the force decreases rapidly. It......

Which Factors are Influencing the Surface Tension of a Liquid?

Factors influencing the surface tension of a liquid: The surface tension of a liquid depends on the following factors: (i) Contamination: If the liquid surface......

What is Cohesive Force?

Cohesive force: We know a certain material consists of some molecules. Attractive force acting between molecules of the same materials is called cohesive force. It......

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 relative motion in general. The property of a fluid......

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 effect of pressure on the co-efficient of viscosity of liquids, if pressure increases; the co-efficient......

Effect of Temperature on Co-efficient of Viscosity in Gases

Effect of temperature on co-efficient of viscosity in Gases The effect of temperature on gases is opposite to that of liquid. In case of gases......

Effect of Temperature on Co-efficient of Viscosity in Liquids

Effect of temperature on co-efficient of viscosity in Liquids Co-efficient of viscosity is affected by temperature. Experimental results show that with the increase of temperature......

Necessity of Viscosity

Necessity of viscosity Viscosity is the measure of a substance’s resistance to motion under an applied force. (1) Design and construction of boats, steamers, launches,......
