Question: A drop of liquid is spherical in shape. This is due to which of the following?

Options:

Correct Answer: Surface tension

Solution:

The spherical shape of a liquid drop is due to surface tension, which minimizes the surface area for a given volume.

A drop of liquid is spherical in shape. This is due to which of the following?

A drop of liquid is spherical in shape. This is due to which of the following?

Step 1: Understand that a drop of liquid is a small amount of liquid that takes a shape.
Step 2: Recognize that liquids have a property called surface tension.
Step 3: Know that surface tension is a force that pulls the surface of the liquid tight.
Step 4: Realize that this force tries to make the surface area of the liquid as small as possible.
Step 5: Understand that the shape with the smallest surface area for a given volume is a sphere.
Step 6: Conclude that this is why a drop of liquid is spherical in shape.

Surface Tension – Surface tension is the property of a liquid that causes it to behave as if its surface is covered with a stretched elastic membrane, leading to the formation of a spherical shape to minimize surface area.
