Chapter 12, Problem 5STP

Interpretation Introduction

Interpretation:

The factor that doesn’t affect viscosity of a liquid must be selected from the given list.

Concept introduction:

Viscosity is an opposing force which resists the flow of liquids or gases.

Answer to Problem 5STP

Correct answer: Option D is correct.

Explanation of Solution

Reason for correct option: Option D is correct because capillary action doesn’t affect viscosity of a liquid.

Conclusion

Reasons for incorrect options: Option A is incorrect as viscosity is affected by intermolecular attractive forces. Higher the force higher is the viscosity.

Option B is incorrect as size and shape of a molecule affects viscosity of a liquid. A spherical object has lesser viscosity as compared to linear object.

Option C is incorrect as viscosity is affected by temperature. With the increase in temperature viscosity of a liquid decreases.
