Question : A liquid distrubed by stirring comes to rest due to
Option 1: density
Option 2: surface tension
Option 3: viscosity
Option 4: centripetal force
Correct Answer: viscosity
Solution : The correct option is viscosity.
When you mix a liquid, it tends to settle over time due to an attribute known as viscosity. Viscosity is a measure of a fluid's resistance to flow. Higher viscosity liquids are thicker and resist motion more, whereas lower viscosity liquids flow more smoothly. As they glide past one another, the liquid molecules near the stirring instrument encounter shear stresses. The mechanical energy is wasted as heat over time as a result of internal friction inside the liquid. This is known as viscous dissipation. The pace at which a liquid comes to rest is affected by several parameters, including viscosity, temperature, and stirring intensity.
