Water has a certain affinity for most gases. This affinity is more pronounced for some gases than for others; for instance, at atmospheric pressure and at ordinary temperatures, pure water will absorb 4 per cent, of its own volume of air, 4 per cent, of its volume of sulphureted hydrogen, or 100 per cent, of its volume of carbonic acid gas.

بیشتر بخوانیدWe presented a new analytic model of physical gas absorption into a stirred liquid. This model is based on the assumption that the gas absorption/desorption process can be considered as a reversible chemical reaction that occurs at the gas–liquid interface. In addition, in this model, there is no assumption about the distribution of the

بیشتر بخوانیدFire hazards are one of the primary risks associated with gas cylinders. These containers carry flammable and oxidizing gases, which can ignite fires if they come into contact with flames or static electricity. Moreover, if a cylinder is exposed to extremely high temperatures, it becomes more susceptible to wear and tear and, consequently, fires.
