Solubility, which influences gases in solution, is dependent on temperature. When using water, increasing the temperature decreases the solubility of gases. This is because whenever the temperature of a gas increases, the kinetic energy of that gas increases as well. This causes intermolecular bonds to break and allows the gas molecules to escape the liquid. The decreased temperature of the liquid causes it to be more oxygen rich.
Liquid breathing is when an organism breathes an oxygen-liquid as opposed to air, this liquid is usually from the perfluorocarbon family. These types of fluorine compound can contain other elements such as hydrogen, chlorine, or bromine. A common property of these liquids is high solubility for respiratory gases. Also, this means that they can contain a large amount of oxygen and carbon dioxide. In addition, the pressure of the gas is …show more content…

As they go deeper into the water the pressure increases forcing the nitrogen molecules closer together, making room for more to be absorbed. When a diver is ready to return to the surface they must do so carefully. In their ascension, pressure lessens and the nitrogen will expand. As the diver's body cannot hold as much nitrogen on the surface as it could in the water they must come up slowly to release the nitrogen. It will go from the body tissues, to the blood, and then be exhaled. If a diver ascends too rapidly, the nitrogen will form bubbles in the blood, travel through arteries, and prohibit blood flow to body parts. This can cause tissue damage, or worse, and is known as decompression sickness. Even if a diver does avoid this, some excess nitrogen will still remain in his body for hours or days after the dive. For this reason, heavy exercise and flying is not recommended after a dive because it will cause the nitrogen to be released to quickly, thus resulting in decompression
