= Bubbles (physics)
{wiki=Category:Bubbles_(physics)}
In physics, "bubbles" refer to enclosed gas pockets surrounded by a liquid or solid substance, typically in the form of a spherical shape. They can be observed in various contexts, including: 1. **Surface Tension**: Bubbles form due to the surface tension of the liquid, which acts to minimize the surface area. This is why bubbles tend to assume a spherical shape, as a sphere has the smallest surface area for a given volume.
