Q.. What are Vicious liquid. Explain briefly?

Viscosity is an internal property of a fluid that offers resistance to flow. It is the measure of the resistance to flow, which arises due to the internal friction between the layers of fluid as they slip past one another while the liquid flows. It is commonly perceived as "thickness", or resistance to pouring.

In simple words, it is the resistance of a fluid to flow. For example, water has a low viscosity, when you pour it, it quickly flows; syrup has a high viscosity; it doesn't pour out nearly as quickly as.
The liquid that show viscosity are called viscous liquids,and those doesnot show are called non-viscous liquids.
​​​Which liquid is the most viscous how do you know:
These can be the condensed milk, honey, paste, glue, cement, seal, toothpaste, oil, grease, liquid soap or detergent soap, and many others. We can distinguish something viscous because of its texture and way of flow.
