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.
Why do vapor bubbles not form in water at room temperature and standard pressure?
we know that water bubbles are formed when external pressure becomes equal to the internal pressure so room temperature is 20 digree to 25 digree and internal pressure deos not equal to external pressure at this temperature so it is clear that vapor bubbles deos not formed in water at room temperature and standard pressure where standard pressure is 760 torr.

Why bubbles come when you add vinegar and crushed chalk?
The reaction between Chalk and Vinegar creates carbon dioxide. Chalk is calcium carbonate and when vinegar is poured on it. It is prepared from water and acetic acid it should fizz up as the oxygen in the acetic acid combines with the calcium carbonate. The foams are carbon dioxide that is formed when the oxygen from the acetic acid links with the carbon from the calcium carbonate.
What gas is formed that could cause bubbles when you mixed flour water sugar and yeast?
