The bubble is called a meniscus. It is caused by surface tension, and usually appears as a curved surface at the top of the liquid in the test tube. To accurately measure the volume of liquid, the measurement should be taken at the bottom of the meniscus.
According to particle theory, a bubble of liquid consists of closely packed particles that are in constant motion. The particles within the liquid are attracted to each other, which creates surface tension at the bubble's interface, allowing it to maintain its spherical shape. The gas inside the bubble consists of particles that are more spread out and move freely, creating pressure against the liquid layer. Overall, the bubble's behavior can be understood through the interactions and movements of these particles.
A spirit level, also known as a bubble level, is a tool used to determine if a surface is horizontal (level) or vertical (plumb). It contains a vial filled with liquid, usually ethanol, with an air bubble that moves to indicate the levelness of the surface being measured.
A bubble is formed when a pocket of air or gas becomes trapped within a liquid or solid material. The surface tension of the surrounding material prevents the bubble from collapsing, allowing it to maintain its spherical shape.
Boiling chips provide a surface on which vapor bubbles can form. This bubble formation helps prevent superheating and bumping of the liquid.
Bubbles are formed due to a combination of surface tension and gas trapped in a liquid. The surface tension of the liquid causes the bubble to retain its spherical shape. When a gas is introduced into the liquid, the surface tension pulls the liquid molecules together around the gas to form the bubble.

An independent variable for a bubble could be the temperature of the liquid in which the bubble is formed. By varying the temperature, researchers can observe how it affects bubble size, stability, or lifespan. Other independent variables might include the type of liquid, the surface tension, or the amount of gas used to create the bubble.
When an air bubble is released underwater, it will rise to the surface due to buoyancy. Buoyancy is the upward force exerted by a liquid on an object immersed in it. As the air bubble rises, the water pressure decreases and the bubble expands in size until it reaches the surface.

Gravity does affect the shape and size of a soap bubble. From the top of my head, an air-borne bubble's surface would have higher density at the bottom (part facing ground).In reality, a bubble is never a perfect sphere and is always heavier at the bottom. If you blow a big bubble and look at it closely, you would likely notice a slight dimp at the bottom of the sphere aka the excess liquid which has accumulated at the bottom due to gravity. This affects the shape of the bubble as the weight of the excess liquid pulls down on the surface area of the sphere.
The bouncing bubble works due to a combination of surface tension and the elasticity of the bubble film. When a bubble strikes a surface, the air inside compresses, and the bubble's film stretches, allowing it to deform without bursting. The cohesive forces between the liquid molecules create a resilient surface that can rebound. This unique property enables the bubble to bounce rather than pop, as long as it retains enough structural integrity during the impact.

Gases cannot form a free surface on their own. However, gases do have a free surface at the boundary between gas and liquid, such as the free surface of the sea, or the boundary between the liquid of a soft drink and each carbon dioxide bubble rising in it.
Bubbles float because they are filled with gas, which is lighter than the surrounding liquid. As air within the bubble diffuses into the liquid, the bubble loses buoyancy and eventually sinks. This process is also influenced by factors like surface tension and pressure differences between the bubble and its surroundings.
