Final answer:
Viscosity measures a fluid's resistance to flow, not the concentration or strength of hydrogen peroxide. It is influenced by intermolecular forces within the fluid. The concept of concentration is related to the amount of a substance in a given volume.
Step-by-step explanation:
The statement that viscosity measures the concentration and strength of hydrogen peroxide is false. Viscosity is actually a measure of a fluid's resistance to flow. High viscosity indicates a greater thickness or resistance, as seen in liquids like motor oil or syrup that do not flow easily. In contrast, water and gasoline, which have low viscosity, flow more freely. Viscosity can be influenced by a liquid's intermolecular forces; the stronger the forces, such as hydrogen bonding, the higher the viscosity. This is different from the concentration of a substance like hydrogen peroxide, which is related to the number of solute molecules in a given volume and can change over time as the substance decomposes.
