How does fluid viscosity affect the sensitivity of the spirit level?

14. How does fluid viscosity affect the sensitivity of the spirit level?

1. A higher viscosity fluid enables the bubble to move more easily
2. A lower viscosity fluid enables the bubble to move more easily
3. Both A and B
4. None of the above

Answer

The correct answer is: B) A lower viscosity fluid enables the bubble to move more easily

Explanation

A lower viscosity fluid enables the bubble to move more easily and react faster to even small inclination changes.
