Yes. Pressue effects both adsorption and absorption of oxygen. I assume you really did mean adsorption (and not absorption) but just in case, this answer addresses both - since the answer is similar.
As pressure increases, the fugacity of oxygen in the liquid or vapor phase will also increase. In order to stay in equilibrium, you would expect the concentration of oxygen on a surface (adsorption) to increase as well. There is one caveat in that if the oxygen is in a mixture, the fugacity of the other components of the mixture will also be increasing and may be in competition with the oxygen for adsorption to the surface. Once the surface is saturated, raising the pressure may not have any effect on the adsorption. Likewise, dropping the pressure will decrease the fugacity of oxygen in the fluid phase and promote desorption from a surface (the reverse of adsorption).
Similarly, increasing or decreasing pressure will increase and decrease the fugacity of oxygen in the vapor phase and require more or less oxygen to be absorbed into a liquid (or in some cases solids - although most solids don't dissolve gasses very well). Increaing pressure can also change the distribution of oxygen between two immiscible liquids as the fugacity of the oxygen in each depends on both pressure and the effect of pressure on the fugacity of the solvent liquids.

What is presure?
Pressure is an effect which occurs when a force is applied on a surface.Mathematically pressure is: p = F / Awhere: * p is the pressure,F is the normal force,A is the area.
In the cylinder valve will burst at a predetermined pressure to prevent the oxygen cylinder from exploding in a fire.?
Yes, oxygen cylinders are equipped with safety features, including a pressure relief valve that will burst at a predetermined pressure. This valve is designed to release excess pressure to prevent the cylinder from exploding in the event of a fire or extreme heat. By venting gas safely, it helps mitigate the risk of catastrophic failure and enhances overall safety. Regular maintenance and inspections are essential to ensure these safety mechanisms function properly.
Why does pressure not have effect on adsorption when the case is solutions on solids?
In the case of adsorption from solutions onto solids, pressure has minimal effect because the adsorption process is primarily driven by concentration rather than pressure. The solute concentration in the solution determines the availability of molecules to interact with the solid surface. As long as the concentration remains constant, increasing pressure does not significantly influence the adsorption equilibrium. Additionally, the solid's surface interactions and the nature of the solute-solvent interactions are more critical factors in this scenario.
How is oxygen concentrated and put in a tank?
Oxygen is concentrated through a process called pressure swing adsorption or cryogenic distillation. The concentrated oxygen is then filled into tanks under pressure to keep it in its gaseous form. The tanks have a valve and regulator to control the flow of oxygen to the user.
Why physical adsorption is reversible process?
adsorption is processs of accumulation of liquid/gases on solid surface. reversible adsorption is seen in physical adsorption where increase in pressure increases the adsorption and decrease in pressure decrease adsorption of molecules to surface that is desorption takes place

How do they capture oxygen into the tank?
Oxygen is captured into tanks through processes like cryogenic distillation, pressure swing adsorption, or membrane technology. These methods involve separating oxygen from the air and compressing it into the tank for storage and later use.

How is oxygen produced commercially?
Various methods have been used for the large scale production of oxygen, but at present the two mostly used are the electrolysis of an aqueous solution of dilute sulphuric acid, and the fractional distillation of Liquid Air.
What is Freundlich adsorption isotherm and Langmuir isotherm?
At a given temperature, the extent of adsorption will increase with the increase of pressure of the gas. The extent of adsorption is measured as x/m, where mi= is the mass of adsorbent and x that of adsorbate. At low pressure, x/m varies linearly with p. As per Freundlich adsorption equation Taking log both sides of the equation, we get, At low pressure, x/m=kP At high pressure, x/m=kPo This is called Freundlich adsorption isotherm at a constant temperature. Freundlich isotherm fails at high pressure and is only for physical adsorption. Langmuir isotherm is represented as x/m=ap/(1+bp) (a and b are constants) At very high pressure,(bp>>1) x/m=a/b At very low pressure,(bp<<1) x/m=ap
Why freundlich adsorption isotherm is not applicable at high pressure?
Freundlich adsorption isotherm assumes a homogeneous surface with a finite number of adsorption sites, making it unsuitable for high pressures where interactions between adsorbate molecules become significant. At high pressures, multilayer adsorption occurs, violating the assumptions of the Freundlich isotherm which fails to account for these complex interactions. As a result, Freundlich isotherm is not applicable in conditions where multilayer adsorption dominates.
Does atmospheric pressure have any effect on the oxygen level in the scuba tank?
No, only when it is released into the atmosphere at the ambient pressure.
How do you make artificial oxygen?
Oxygen is an element and it is not easy to make elements artificially.You can make artificial oxygen carriers that carry oxygen in the blood instead of hemoglobin.
What are the disadvantages of Frenlich adsorption isotherm?
Frenlich adsorption isotherm has no theoretical basis. There are high chances of it failing when the concentration of the adsorbate is high. The equation is, usually, invalid at high pressure.
