Chapter 7, Problem 76P
Interpretation Introduction
Interpretation:
The reason due to which a needle floats when it is carefully placed on the water surface and sinks when its tip is pushed needs to be explained.
Concept introduction:
Viscosity is defined as the measuring unit of resistance of deformation of fluid at given rate.
The surface tension is defined as the tension which is created by the attraction of the particles of the fluid on the surface. The surface tension of fluid reduces the surface area.
