The angle of contact between glass and mercury is
Text Solution
Verified by ExpertsThe correct answer is:
A
Step 1: The angle of contact, also known as the wetting angle, is the angle formed between the tangent to the liquid surface and the solid surface at the point of contact.
Step 2: For mercury, which is a non-wetting liquid with respect to glass, the angle of contact is typically very small.
Step 3: In the case of mercury and glass, the angle of contact is approximately 0°, which means that mercury does not wet the surface of glass.
Therefore, the correct answer is: A.
