Honey flows slower than that of water due to its higher _____.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Viscosity
Viscosity is the internal friction of a fluid: the resistance its layers offer to sliding over one another. Honey has a much higher viscosity than water, so its layers drag on one another more and it flows slowly.
Why the other options are incorrect
Option (1) Pressure — Incorrect. Pressure is force per unit area; it does not decide how freely a liquid flows.
Option (3) Moment of Inertia — Incorrect. It measures a body’s resistance to a change in rotation, not the flow of a liquid.
Option (4) Thermal conductivity — Incorrect. It is the ability to conduct heat, which has nothing to do with the speed of flow.
