Before to learn or to know surface energy students must know surface tension. To know about the surface tension click here- Surface energy- It is given as the work done to increase the unit area of a liquid .Or, It is the energy required to remove a molecule completely from a liquid. Or, The molecules at […]
Surface tension– It is the property of a free surface of liquid to get minimum surface area . The property of a liquid at rest by virtue of which its free surface behaves like a stretched elastic membrane and tries to occupy as small an area as possible called surface tension. As we know in […]

In Maths, integration is a method of adding or summing up the parts to find the whole. It is a reverse process of differentiation, where we reduce the functions into parts. This method is used to find the summation under a vast scale. Calculation of small addition problems is an easy task which we can […]
