Specific strange Gravity

I have never setup a problem like this before. I want to show the pressure on the water from the gas bubble.

I was thinking of lava tubes in the ocean at shallow depths. When C and S gasses are released from the surface their temperature instantly raises the temp of the H₂O to several thousand degrees. So all particles inside the bubble are gasses; our carbon is >3550°C. Specific gravity within the bubble causes the particles to layer and cool according to density. When the Carbon temp drops below 3550°C it exits the gas bubble and floats in the ocean. Likewise when the Sulfur temp drops below 115.21°C it exits the gas bubble and falls. The sulfur falls because it is more dense than the H₂O or Carbon. Some of our H₂O bubble manages to cool to 105°C at the surface causing bubbles. The H₂O is still a gas when entering the atmosphere and instantly cools to the air temperature. The H₂O condenses to a liquid drop eight feet above sea level and is hit by a wave.

This is an example of temperature assisted density driven specific gravity. But here the particles are not falling to meet the more massive earth. They are rising to their level of density.
