Develop a hypothesis to explain why bubbles exhaled by scuba divers underwater expand as they float up to the surface of the ocean. ​

The bubbles exhaled by a scuba diver grow as they approach the surface of the ocean. The pressure exerted by the weight of the water decreases with depth, so the volume of the bubbles increases as they rise.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
