Viscosity is the internal resistance to the flow possessed by a liquid. The internal resistance depends upon the intermolecular attractive forces. Liquids which flow rapidly have low internal resistance, small intermolecular forces and low viscosity. Glass is an extremely viscous liquid, hence, its properties resemble to that of solids.
Assertion: Viscosity of the liquid decreases with decrease in temperature.
Reason: Kinetic energy of the molecules increases with increase in temperature.
- a)A and R both are correct and R is the correct explanation of A.
- b)A and R both are correct but R is not the correct explanation of A.
- c)A is true but R is false.
- d)A is false but R is true.
Correct answer is option 'D'. Can you explain this answer?

Understanding Viscosity
Viscosity refers to a liquid's internal resistance to flow, which is significantly influenced by intermolecular forces. Generally, when these forces are weak, the liquid flows easily, resulting in low viscosity. Conversely, strong intermolecular forces lead to higher viscosity.
Assertion: Viscosity of the liquid decreases with decrease in temperature.
- This statement is false.
- In fact, viscosity typically increases as temperature decreases because the kinetic energy of molecules diminishes. As the temperature drops, molecules move less vigorously, increasing the internal resistance to flow.
Reason: Kinetic energy of the molecules increases with increase in temperature.
- This assertion is true.
- As temperature rises, the kinetic energy of the molecules also increases, which leads to more vigorous molecular motion. This increased movement reduces the intermolecular forces' effect, thereby decreasing the viscosity.
Conclusion
- The correct answer to the question is option D: "A is false but R is true."
- The assertion about viscosity decreasing with a decrease in temperature is incorrect, while the reason regarding the increase in molecular kinetic energy with temperature is accurate.
This distinction highlights the importance of understanding the relationship between temperature and viscosity in liquids, which is crucial for various scientific applications.
