Surface tension
The soap bubble attains a spherical shape due to surface tension. Surface tension is the property of a liquid that allows it to resist external forces. In the case of a soap bubble, the surface tension of the soapy water forms a thin film that encloses the air inside.
Explanation
- When soap is added to water, it reduces the surface tension of the water.
- The surface tension of the soapy water tries to minimize the surface area, so it pulls the water molecules closer together.
- This creates a thin film of soapy water with the least surface area, which encloses the air inside the bubble.
- The surface tension acts equally in all directions, which is why the bubble takes on a spherical shape as it minimizes the surface area.
Other factors
- Inertia: Inertia is the tendency of an object to resist changes in its state of motion. While inertia plays a role in the movement of the bubble, it does not directly contribute to its spherical shape.
- Pressure: Pressure can affect the size and stability of the bubble, but it is not the primary factor in determining the spherical shape.
