Question: If a drop of liquid is placed on a flat surface, what shape will it take due to surface tension?

Options:

Correct Answer: Sphere

Solution:

Due to surface tension, a drop of liquid will take the shape of a sphere, as this shape has the minimum surface area for a given volume.

If a drop of liquid is placed on a flat surface, what shape will it take due to surface tension?

If a drop of liquid is placed on a flat surface, what shape will it take due to surface tension?

Step 1: Understand that a drop of liquid is made up of many tiny molecules.
Step 2: Know that these molecules are attracted to each other, which creates a force called surface tension.
Step 3: Recognize that surface tension tries to minimize the surface area of the liquid drop.
Step 4: Realize that a sphere has the smallest surface area for a given volume compared to other shapes.
Step 5: Conclude that because of surface tension, the drop of liquid will form a spherical shape.

Surface Tension – The cohesive force between liquid molecules that causes the liquid to minimize its surface area.
Shape of Liquid Drops – A drop of liquid adopts a spherical shape due to surface tension, as a sphere has the least surface area for a given volume.
