Q.No.6.1:- Explain what do you understand by the term viscosity?

Ans:-      From the microscopic study of flowing fluid we know that fluid flows when the layers of fluid slid over on another. But there exists another opposing force between the layers of fluid which wants to stop this sliding. This force is called the viscosity.

    In short we can say that viscosity is the opposing force (frictional effects between the relative motion of layers of fluid) between the layers of fluid which will slow down the flow of fluid or stop it if it is very large.
