Background: Higher pressures increase the solubility of gases. You are probably familiar with this concept as it relates to carbonated beverages. Before opening the container, the inside is pressurized, so a large amount of CO 2 is dissolved in the liquid. After opening, the pressure decreases (to the ambient pressure), so the solubility of CO 2 drops, causing it to bubble out of solution. Because they are not compressible like gases, solid and liquid solutes do not have noticeable changes in solubility at different external pressures.

Situation: Jane worked at a bottling company she liked her job but her favorite thing was to watch as carbon dioxide was added to the soda to make it fizzy. Today she grabbed a cola on her way to break. When she opened the can and poured it into a cup she hear a fizzing sound and saw the soda bubbling in the glass. She got to talk and forgot about her drink when she took a sip later the soda was flat, there was no carbonation left.
