How does temperature affect the solubility of gases like nitrogen?

Higher temperatures decrease gas solubility in liquids due to the increased kinetic energy of molecules. As temperature rises, the energy of the gas molecules also increases, causing them to move more vigorously. This heightened motion makes it more difficult for gas molecules to remain dissolved in the liquid, resulting in a lower solubility. For divers, this is particularly important when considering the absorption of nitrogen in body tissues—warmer water temperatures could lead to less nitrogen being absorbed, which may influence the risk of decompression sickness upon ascent.

The relationship between temperature and gas solubility is essential for understanding dive planning, as divers must take temperature into account when determining their exposure limits to various gases, including nitrogen. Understanding this principle helps divers to manage their ascent rates and avoid complications associated with nitrogen narcosis or the bends.
