Which material has the lowest viscosity?

acetone (fingernail polish remover)

motor oil

glue

syrup

Option (a) is the correct answer.

Explanation:

Viscosity is defined as the ability of a substance to have difficulty in changing its shape or difficulty in the movement. This means that a substance which is able to flow easily will have low viscosity.

For example, acetone has low viscosity as it is a volatile substance.

On the other hand, a substance that is able to flow with difficulty will have high viscosity.

For example, glue, syrup, motor oil etc are substances that find difficulty in flowing. Hence, they have high viscosity.

Thus, we can conclude that out of the given options acetone (fingernail polish remover) is the material has the lowest viscosity.
