A liquid drop is formed on a surface. The angle formed between the tangent to the drop surface and the solid surface is called what?
Contact angle
Surface angle
Tension angle
Cohesion angle
The angle formed between the tangent to the drop surface and the solid surface is known as the contact angle, which indicates the wettability of the surface.

Q: A liquid drop is formed on a surface. The angle formed between the tangent to the drop surface and the solid surface is called what?
Solution: The angle formed between the tangent to the drop surface and the solid surface is known as the contact angle, which indicates the wettability of the surface.
Steps: 7
Step 1: Understand that a liquid drop can form on a solid surface.
Step 2: Identify the point where the liquid drop meets the solid surface.
Step 3: Imagine a line that is tangent to the surface of the liquid drop at that point.
Step 4: Now, look at the solid surface where the drop is resting.
Step 5: The angle formed between the tangent line of the drop and the solid surface is what we are interested in.
Step 6: This angle is called the contact angle.
Step 7: The contact angle helps us understand how well the liquid spreads on the surface, which is known as wettability.
