While they may exist in any phase, liquid and gaseous solutions are the most commonly studied solutions in chemistry. If the diver ascends too quickly, the rapid pressure change causes small bubbles of N2 to form throughout the body, a condition known as “the bends.” These bubbles can block the flow of blood through the small blood vessels, causing great pain and even proving fatal in some cases. Henry’s law also explains why scuba divers have to be careful to ascend to the surface slowly after a dive if they are breathing compressed air. Effect of Temperature on the Solubility of Gases. Figure 1. The effect of temperature on solubility depends on the type of reaction that occurs during the process of dissolving the solute in the solvent. in equilibrium with the normal partial pressure of \CO_2\) in the atmosphere (approximately \(3 \times 10^{-4} \;atm\)).
