Date/Time Thumbnail Dimensions User Comment; current: 09:01, 4 January 2010: 952 × 1,431, 18 pages (4.8 MB): Ayacop {{Information |Description={{en|1=original paper resulting in Henry's law, one of the gas laws}} |Source=William Henry: ''Experiments on the Quantity of Gases Absorbed by Water, at Different Temperatures, and under Different Pressures'' Phil. Trans. R.
The solubility of gas obeys Henry's law, that is, the amount of a dissolved gas in a liquid is proportional to its partial pressure. Therefore, placing a solution under reduced pressure makes the dissolved gas less soluble. Sonication and stirring under reduced pressure can usually enhance the efficiency.
Measurements of primary productivity in the ocean can be made using this ratio. The concentration of oxygen dissolved in seawater varies according to biological processes (photosynthesis and respiration) as well as physical processes (air-sea gas exchange, temperature and pressure changes, lateral mixing and vertical diffusion).
Marine chemistry, also known as ocean chemistry or chemical oceanography, is the study of the chemical composition and processes of the world’s oceans, including the interactions between seawater, the atmosphere, the seafloor, and marine organisms. [2]
Inert gas such as nitrogen or helium continues to be taken up until the gas dissolved in the diver is in a state of equilibrium with the breathing gas in the diver's lungs, at which point the diver is saturated for that depth and breathing mixture, or the depth, and therefore the pressure, is changed, or the partial pressures of the gases are ...
dissolved gases – oxygen levels in particular, can be increased by wave actions and decreased during algal blooms; acidity – this is partly to do with dissolved gases above, since the acidity of the ocean is largely controlled by how much carbon dioxide is in the water.
4. All of the terms in this category precede a common three-letter noun (hint: the word typically refers to a small container that's used for drinking). Related: 300 Trivia Questions and Answers ...
Once dissolved, distribution of the dissolved gas is by perfusion, where the solvent (blood) is circulated around the diver's body, and by diffusion, where dissolved gas can spread to local regions of lower concentration when there is no bulk flow of the solvent. Given sufficient time at a specific partial pressure in the breathing gas, the ...
