Question

Whether a certain liquid is the upper or lower layer depends upon the

a) Temperature
b) Density
c) Pressure
d) Viscosity

Answer 1

The correct answer is (d) Viscosity. Whether a certain liquid is the upper or lower layer in a mixture depends on its viscosity.

Step-by-step explanation:

The correct answer is (d) Viscosity. Whether a certain liquid is the upper or lower layer in a mixture depends on its viscosity. Viscosity refers to the resistance of a liquid to flow. Liquids with higher viscosity have stronger intermolecular forces and flow more slowly, causing them to settle at the bottom and form the lower layer. Liquids with lower viscosity flow more easily and form the upper layer.
