Answer 2

a. H₂ is the correct answer.

Explanation:

• Viscosity is defined as the resistance to flow. At a molecular level, viscosity is a result the interaction between molecules in a fluid. This can be also understood as friction between the molecules in the fluid.
• As viscosity increases, low rates decrease. As general rule, further the fluid is from the pump, the lower the flow rate will be. The viscosity of a fluid is a measures of its resistance to deformation at a given rate.
