Question

one drop each of water,kerosene and honey are placed at different position on a glass plate and tilted
a)which drop flows down fast and which one flows slower
b)why does it flows fast compared to others​

Answer 1

Answer:

the kerosene will flow the fastest and honey will flow slowest

Answer 2

Answer:

Water will reach the bottom first, then, the kerosene and then the honey.

Explanation:

a) Water will reach the bottom in the least time and honey will take the most time. Kerosene will take lesser time than honey but more than water.

b) Reason:

The viscosity of a fluid is a measure of its resistance to deformation. Its unit is Poiseuilli(pC) or newton-second per square meter.

Viscosity quantifies the internal frictional force between adjacent layers of fluid that are in relative motion. Viscosity denotes opposition to flow.

More the viscosity of a fluid, more is the opposition to its flow, more time it will take to flow.

The viscosity of honey is 10,000 cP at room temperature.

The viscosity of kerosene is 2.17 cP at room temperature.

The viscosity of water is 1 cP at room temperature.

Hence, Water will reach the bottom first then the kerosene then the honey.
