Bubbles form in a spherical shape because it is the most efficient method of containing a volume - the surface area is lowest, compared to other shapes, cubes, ovals etc. Also, the bubble has no specific weak points, all points on the surface share the same properties, and so there is less tendency to burst.

area of a circle = area of a rectangle(parallelogram) formed by the sectors of circle with pi as length and radius as bradth.
It is 90 degrees between the circle's diameter and its tangent

Bubbles are formed from soap when they are mixed with water and there is air. When air is present and water is mixed with soap, bubbles will definitely form.

air bubbles in pancakes are formed because the carbon dioxide is less dense then the pancake batter.
Bubbles in fizzy drinks are formed from carbon dioxide gas CO2; the internal pressure of bubbles can be great.

White caps form on waves when strong winds cause the water to break more vigorously, creating frothy foam or spray on the wave tops. This occurs when the wind speed surpasses a certain threshold, making the wave crests unstable and causing them to break into white caps.
Carbon dioxide is the gas formed during fermentation when you mix flour, water, sugar, and yeast. This gas causes the dough to rise and creates bubbles in the mixture.
Biological molecules were trapped in molecular bubbles. Cell like structures formed from molecular bubbles-apexx
The bubbles of a soap has no colour compared to the soap because when the soap mixes with the water it looses its colour and the bubbles formed are colourless.
spheres are the 3-d figures which have least energy so bubble tend to be round in a circle
Bubbles are formed when chalk is dipped in water due to the release of carbon dioxide gas. Chalk is made of calcium carbonate, which reacts with the water to produce carbon dioxide gas bubbles. This reaction is known as effervescence.
