Illustrations of Capillarity
Illustrations of capillarity: (i) A blotting paper absorbs ink by capillary action. The pores in the blotting paper act as capillaries. (ii) The oil in…

Define Capillarity
The property of surface tension gives rise to an interesting phenomenon called capillarity. When a capillary tube is dipped in water, the water rises up…
Excess Pressure inside a Soap Bubble
A soap bubble has two liquid surfaces in contact with air, one inside the bubble and the other outside the bubble. In balance, the air…
Excess Pressure inside a Liquid Drop
Consider a liquid drop of radius r, and surface tension T. The molecules on the surface of the drop experience a resultant force acting inwards…
Angle of Contact in Surface Tension
When the free surface of a liquid comes in contact with a solid, it becomes curved at the point of contact. The angle between the…
Relation between Surface Energy and Surface Tension
The potential energy per unit area of the surface film is called surface energy. Consider a metal frame ABCD in which AB is movable. The…
Surface Tension of a Liquid
Surface tension is the property of the free surface of a liquid at rest to behave like a stretched membrane in order to acquire minimum…
Define Molecular Range and Sphere of Influence
Molecular range is the maximum distance up to which a molecule can exert the force of attraction on another molecule. It is of the order…
Surface Tension of Intermolecular Forces
The force between two molecules of a substance is called intermolecular force. This intermolecular force is basically electric in nature. When the distance between two…
Practical Applications of Viscosity
Viscosity is like a frictional force. It is an essential property of fluids which describes a liquids confrontation to flow and is related to the…
