Under a certain temperature and pressure, the highest amount of gas dissolved in a certain amount of solvent is called the solubility of the gas. The solubility of gases is not only related to the nature of the gas and the properties of the solvent, but also related to temperature and pressure. Its solubility generally decreases as the temperature increases.

The bubbles come out and then dissolve back to cool down, but this is generally useless. The bubbles are pretty good-looking, so don’t think of ways to trouble yourself to remove them.
