Small liquid drops are spherical due to the property of surface tension. This property is known as, The pressure inside a soap bubble and that outside it are not identical due to surface tension of the soap bubble. A small air bubble of radius r in water is at a depth h below the water surface. Physics Handwritten Notes For Class 11 For a soap bubble in air, there are two surfaces. So, that is how much energy or how much force do we need so that these molecules will start to pull away from each other so that we can go right through the surface of the water. Now, as the plane liquid surface in the tube acquires a curvature, (i.e. It contains the important ideas of class-lecture and book. R, because now h = l, the length of the tube (a constant) and so is q a constant for the given liquid and the tube.

This energy is derived from the depression of the liquid inside the tube, whose gravitational potential energy is thus decreased by an equal amount. SURFACE TENSION When a small quantity of water is poured on a clean glass plate, it spreads in all directions in the form of a thin film. Here we see a water strider on the liquid water, so that’s the idea of surface tension. One of our academic counsellors will contact you within 1 working day. Well, the water or other liquids, the surface tension is different for different liquids. Consider a glass capillary of radius R dipped in water as shown in the figure. If q be the angle of contact between the liquid and the tube, and R, the radius of liquid meniscus in the tube, we have r = R cos q, where r is the radius of the tube; so that above relation now becomes, where h is the height of the liquid column in the tube. Energy expended will be the work done against the increase in surface area, i.e. This animaition is used to show size as a comparison with depth. “Surface tension is the property of a liquid by virtue of which its free surface behaves like a stretched membrane and supports, comparatively heavier objects placed over it”.

The pressure below the meniscus will be (p0 - 2T/r). 1. The work done to from a film is stored as potential energy in the surface and the amount of this energy per unit area of this surface under isothermal condition is the "intrinsic surface energy" or free surface energy density. , Currently we provide the details for Technical Articles ,Lecture Notes,Question paper , seminar topics, project topics etc. 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 surface area. If q < 90o, the meniscus will be convex, for illustration: at a mercury-glass interface. Surface Tension Problems. The liquid thus just spreads over the walls of the tube at the top and its meniscus acquires a new radius of curvature R', such that R'l = 2T/ρg, or that R'l = R.h = a constant. And since l is smaller than R' > R, i.e., the meniscus becomes less curved. A film of liquid is formed on it. The CGS unit of coefficient of viscosity y is poise, its dimension is ML, x is the distance of the free surface with respect to the fixed surface, When a smooth sphere of radius r moves with a velocity v through a fluid of viscosity, , the viscous force opposing the motion of the sphere is.

Now, viscosity. Practice JEE Main Physics Revision Notes solved by our expert teachers helps to score good marks in IIT JEE Exams. i.e. When such liquids are put into a solid tube, a convex meniscus is obtained. It is also useful for class 11 and class 12 (board exam s). Download Pdf. The radii of the two columns is U-tube are r1 and r2. And therefore, decrease in surface area = n4Πr2 - 4ΠR2 and, => decrease in surface energy = (n.4Πr2 - 4ΠR2), Hence, heat produced = (n.4Πr2 - 4ΠR2) T/J, This heat is obviously taken up by the single drop formed of volume 4/3 ΠR3 and hence of mass 4/3 ΠR3 × 1 taking density of water to be 1000 kg/m3, If therefore, θoC be the rise in temperature, we have, (4/3 ΠR3 × 1) × 1000 × θ = (n.4Πr2 - 4ΠR2)T/J, Now, volume of the single drop = volume of n droplets, so that, θ = 3T/J (1/r - 1/R) × 10-3 [substituting the value of R3]. We have seen, how a liquid rises up into a capillary tube, dipped into it, until the weight of the liquid in the tube is just balanced by the force due to its surface tension. It could be a lot of things that you think of when we think of viscosity. : Union HRD Minister launches an AI-powered mobile app for mock tests of JEE will prove extremely useful JEE!
