A cup with a hole in the bottom drains slower when filled with honey than when it is filled with water. This is because of
- a)presence of impurities in the water.
- b)the higher gravitational pull on water.
- c)the difference in viscosities of honey and water.
- d)stronger capillary effect in case of honey.
Correct answer is option 'C'. Can you explain this answer?

A cup with a hole in the bottom drains slower when filled with honey ...
- If a cup with a hole in the bottom is taken and honey is poured into it, it is found that the cup drains very slowly. If the same cup is filled with water, the cup drains much more quickly. This is because honey's viscosity is large compared to water's viscosity.
- Viscosity is a measure of a fluid's resistance to flow. It describes the internal friction of a moving fluid. A fluid with large viscosity resists motion because its molecular makeup gives it a lot of internal friction. A fluid with low viscosity flows easily because its molecular makeup results in very little friction when it is in motion.
- Hence option (c) is the correct answer.

A cup with a hole in the bottom drains slower when filled with honey ...
Explanation:
When a cup with a hole in the bottom is filled with honey, it drains slower compared to when it is filled with water. This is primarily due to the difference in viscosities between honey and water.
Viscosity:
Viscosity is a measure of a fluid's resistance to flow. Honey has a much higher viscosity than water. Viscosity is influenced by factors such as temperature, impurities, and molecular properties of the fluid.
Viscosity of Honey:
Honey is a thick, sticky substance that flows slowly. It has a higher viscosity due to its composition, which includes sugars, proteins, and other dissolved substances. The presence of these compounds makes honey thicker and more resistant to flow.
Viscosity of Water:
Water, on the other hand, has a much lower viscosity compared to honey. It is a thin, less viscous liquid that flows easily. The molecular structure of water allows it to flow more freely, resulting in a lower resistance to flow.
Impact on Drainage:
When a cup with a hole in the bottom is filled with honey, the higher viscosity of honey slows down the drainage process. The thick consistency of honey creates more resistance to flow, making it harder for the honey to flow out of the cup through the hole.
In contrast, when the cup is filled with water, the lower viscosity of water allows it to flow more easily through the hole. The water encounters less resistance, leading to a faster drainage rate compared to honey.
Conclusion:
The difference in viscosities between honey and water is the primary reason why a cup with a hole in the bottom drains slower when filled with honey. The higher viscosity of honey creates more resistance to flow, resulting in a slower drainage rate.
