Homonym: bubbles (Spheres)
Bubbles are small, spherical pockets of gas that are surrounded by a thin layer of liquid. They can form in various liquids, such as water or soap solutions, when air is trapped. Bubbles are often seen in everyday life, like in carbonated drinks or when blowing soap bubbles. The surface tension of the liquid helps maintain the bubble's shape, allowing it to float or rise.
Bubbles can also occur in nature, such as in boiling water or during the process of fermentation in yeast. In these cases, gas is produced and forms bubbles that escape into the air. Bubbles play a role in many scientific and industrial processes, including aeration in water treatment and emulsification in cooking.
