- Statement I is correct but Statement II is incorrect
- Statement I is incorrect but Statement II is correct
- Both Statement I and Statement II are incorrect
- Both Statement I and Statement II are correct
Show Solution
The Correct Option is B
Solution and Explanation
An individual examination of each statement regarding its underlying physics concepts is presented below:
- Statement I: The viscosity of gases exceeds that of liquids.
- Viscosity quantifies a fluid's resistance to flow. Typically, liquids exhibit higher viscosity than gases. This is attributed to the closer proximity and stronger intermolecular interactions in liquids compared to gases, where molecules are widely separated with minimal interactions.
- Consequently, this assertion is factually inaccurate.
- Statement II: The surface tension of a liquid is diminished by the presence of insoluble impurities.
- Surface tension is a characteristic property reflecting the cohesive forces at a liquid's surface. Insoluble impurities introduced to the surface can disrupt these cohesive forces among liquid molecules, leading to a reduction in surface tension.
- Therefore, this statement is accurate.
Based on these analyses, Statement I is determined to be incorrect, while Statement II is accurate. The optimal selection is thus:
The correct answer is: Statement I is incorrect but Statement II is correct.
