Which of the following statements is true?
A) The higher the viscosity, the faster a liquid flows.
B) The viscosity increases with increasing temperature.
C) The stronger the intermolecular forces, the higher the viscosity.
D) Hydrogen bonding in water gives rise to its unusually low viscosity.
E) The viscosity of gases is larger than the viscosity of liquids.

Question

Quizplus · Accepted Answer

Viscosity is a measure of a liquid's resistance to flow. The stronger the intermolecular forces between the molecules of a liquid, the harder it is for the molecules to move past each other and the higher the viscosity. Temperature has the opposite effect, as increasing temperature increases the kinetic energy of the molecules, making them move faster and reducing viscosity. Hydrogen bonding actually contributes to water's unusually high viscosity, making D incorrect. Choice A is incorrect because higher viscosity means slower flow, and E is incorrect because gases typically have lower viscosity than liquids.
