Answer to Question 1

ANS: A
Viscosity is influenced by the strength of the cohesive forces between the molecules and an ob-ject's density.

Answer to Question 2

ANS: B
Specific gravity calculations use Archimedes principle in comparing a substance's weight and density relative to a standard. The measurement of specific gravity can also be applied to gases.
