Question

Of these four liquids, which is the most viscous?

Answer 1

Answer: Option (d) is the correct answer.

Explanation:

Viscosity is defined as the ability of a fluid to resist its flow. That is, more thicker a fluid is less likely it is able to flow with ease.

For example, viscosity of honey is high as compared to water.

Whereas water at room temperature, ethyl alcohol at room temperature, and hot motor oil can flow easily.

Thus, we can conclude that out of the given options, honey at room temperature is the most viscous.

Answer 2

I believe the correct answer from the choices listed above is the last option. Of these four liquids, the most viscous one is honey at room temperature. Honey is made up of sugars and the hydrogen of the sugars and water is what makes it more viscous.
