The difference between dissolution and absorption, ask for advice
The concept is different.The dissolving refers to the solid object to enter the liquid solution to form a solution. It itself is much smaller than the same temperature and the lower gas substance. When heating, the solubility of the solubility in liquid solution is much greater than the escape speed.The gas is the opposite. Does absorption refer to the gas phase substances entering liquid solution?EssenceIn short, no matter which one is a dynamic balance process.Can this understand this?

The dissolution is only because it can be dissolved in the solvent and changes from solid -state to ions. It is only a physical change. Reactions have undergone chemical changes and generate new substances. Solid bodyThe main influencing factors in the process of liquid and gases in the process of dissolving and absorption are temperature and pressure, and the nature of its own structure and solvent The higher the temperature, the more it is not conducive to absorption; the higher the pressure, the more it is conducive to absorption Most solid substances such as gas, calcium hydroxide, and calcium carbonate absorb calories when soluble in water. According to the principle of balanced moving, the balance is conducive to moving in the direction of heat absorption. ThereforeIncrease with temperature, such as KNO3, NH4NO3, etc.There are a few substances, which are indoor when dissolving. Generally speaking, their solubility decreases with the increase of temperature, such as CA (OH) 2, etc.The higher the material temperature, the lower the solubility.

Solubility: Generally refers to solid dissolving in liquid; Absorption: Generally refers to gas dissolved in liquid; Absorption of physical absorption and chemical absorption. For ordinary objects, the higher the temperature, the more conducive it is to dissolve and is not conducive to absorption. There are also some substances that decreased with the degree of dissolving.

The principle of chemical industry is clearly white. The principle of gas absorption is that the solubility of each component in a mixed gas to separate the mixture mixture in the solubility of a certain liquid.(The \"competitive\" absorption of liquid-liquid is generally called extraction, and it is also based on different solubility. The principle of immersion is also the solubility of components in solids in the solvent.) So, (gas) absorption process must be a solubility process, but the dissolving process is not necessarily (gas) absorption. Generally, cooling can improve the solubility of gas solubility, which is of course conducive to absorption (on the contrary, heating up is conducive to suction). I think that the impression of the textbooks in the junior high school is that solids are soluble in the liquid and are generally a physical reaction process. This is a narrow \"dissolved\" concept.Gas and liquids are dissolved in solvents (chemical absorption or physical absorption, physical extraction, chemical extraction) are all \"concepts\" on the \"broad sense\".
