Assertion: The contact angle between water and glass is acute.
Reason: The surface of water in the capillary is convex.

View answer and explanation

Correct option: C

If assertion is true but reason is false

Option C is correct because the contact angle between water and glass is acute, but the surface of water in a capillary is concave, not convex.
