air bubbles in pancakes are formed because the carbon dioxide is less dense then the pancake batter.
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
As the flask expands,hor air is being pushed out,therefore,air bubbles are formed.
Bubbles of air dissolved in the water.
Hot air trapped underneath that forces it's way through. A good example of that would be the bubbles in pancakes.
due to capillary action water raises in chalk.. and the air in it comes out in form of bubbles...
When an inverted mug is put in a bucket of water it is not empty. It has air in it. When the mug is tilted the air escapes to the surface, this air is the bubbles you refer to.
bubbles
To remove the air bubbles, open the stopcock and the air bubbles will remove
It is the water vapor that is formed inside the bubbles. Water is lost in the air in the form of water vapor.
there is vacuum inside the air bubble. since air bubles are formed on the principle of marangoni's Theorem ( surface tension), the water molecules aquire the spherical shape of the bubbles quickly, leaving no air inside the bubble..... the air bubbles or the soap bubbles are used to solve many space and gravity related problems... i hope i have provided u with the correct solution....
air bubbles,colour change,go look on bitesize
