Will the powder in the hot air cushion melt?

Will the powder in the hot air cushion melt? The solubility of gas in water decreases with the increase of temperature, so when water is heated, it will ... it doesn't have to reach the boiling point to bubble. When you heat cold water, the gas dissolved in the water will precipitate. . There is water vapor in the air in the air cushion ~ ~! ~! Water vapor will liquefy when it is cold. Ps: Every substance has a specific temperature. Above this temperature, no matter how the pressure increases, gaseous substances will not liquefy. This temperature is the critical temperature. . It can only prevent dryness in the house and moisturize the skin. A certain amount of gas is dissolved in water. When the temperature rises, the solubility decreases, and the gas will be separated from the water, so bubbles will be formed. Similarly, the oxygen content in the water decreases, and the fish should swim close to the surface. . It's related to temperature. When the temperature is high, oxygen is difficult to dissolve in water, so the oxygen content is low; When the temperature is low, oxygen is easily soluble in water and has high oxygen content. When heating cold water, because the water temperature rises, the oxygen dissolved in water is less, and the oxygen will overflow, so it becomes the bubble that the landlord sees. Similarly, the oxygen content in the pond in summer is lower than that in winter, so the fish swarm is due to ... sweating when the temperature is high, which is the way for the body to regulate its body temperature. The same person should sweat as much at the same temperature, but the difference is that in sultry weather, because of the high air humidity, sweat is difficult to evaporate and new sweat is constantly formed, so I feel sweating more. . The higher the water temperature, the less dissolved air. When water is very hot, air becomes bubbles. Bubbles don't have to reach boiling point. In summer, the water in the pond is also hot, and there is little air inside. Fish can breathe air on the water. 1. Of course, some other gases, such as oxygen and carbon dioxide, dissolve in water and come out during heating. 2. When the weather is sultry, the solubility of oxygen in water decreases, which reduces the dissolved oxygen content in water, so fish naturally surface when oxygen is insufficient. This is night sweats. You should take some medicine. (Qi Xing Khan stops)
