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.
By air
bubbles
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.
cell membrane
because it is formed by bubbles
Yeast exhales CO2 as it breathes, therefore the bubbles formed are likely to be CO2.
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
due to capillary action water raises in chalk.. and the air in it comes out in form of bubbles...
