Question

Given below are two statements:
Statement I: Pressure of a fluid is exerted only on a solid surface in contact as the fluid-pressure does not exist everywhere in a still fluid.
Statement II: Excess potential energy of the molecules on the surface of a liquid, when compared to interior, results in surface tension.
In the light of the above statements, choose the correct answer from the options given below

• A. Both Statement I and Statement II are false
• B. Statement I is true but Statement II is false
• C. Both Statement I and Statement II are true
• D. Statement I is false but Statement II is true

Hint:

Fluid pressure exists at every point inside a fluid, while surface tension originates from unbalanced intermolecular forces at the liquid surface.

Answer 1

The Correct Option is A

Step 1: Analyze Statement I.
Statement I is incorrect because fluid pressure exists at every point inside a fluid at rest and acts equally in all directions. It is not limited only to solid surfaces in contact.
Step 2: Analyze Statement II.
Statement II is incorrect. Surface tension arises due to unbalanced cohesive forces acting on surface molecules, not due to excess potential energy alone.
Step 3: Conclusion.
Since both Statement I and Statement II are incorrect, the correct option is (A).
Final Answer: \[ \boxed{\text{Both Statement I and Statement II are false}} \]
