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.
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.
Is pressure increased or decreased when the soda can is opened??
