Please asians dont answer this question you piss me off

As water temperature increases, gas solubility decreases

Oxygen typically enters water when water runs over rocks and creates tremendous amounts of surface area. The high surface area allows oxygen to transfer from the air into the water very quickly.
In a healthy ecosystem, the rates of oxygen transfer (being used up by organisms) and oxygen uptake are balanced in the water. Water has a natural attraction to oxygen. When oxygen comes in contact with the surface of water, the oxygen tends to enter the water, becoming dissolved oxygen.
The amount of attraction between oxygen and water depends on the amount of oxygen already in the water. If there is very little oxygen in water, then the water is very attractive to oxygen. When water has a high concentration of dissolved oxygen, then the water is saturated. Saturated water is not very attractive to oxygen. Water's attractiveness to oxygen also depends on the concentration of oxygen in the air coming in contact with the water; the higher the concentration of oxygen in the air, the greater the attraction of the oxygen to the water. The greater the difference between the oxygen concentration in the air and the dissolved oxygen concentration in the water, the faster the oxygen will move into the water. So if there is very little oxygen in the water, oxygen will dissolve into the water very quickly.
There is a strong connection between temperature and dissolved oxygen. Any activity that changes the temperature of water is also affecting the dissolved oxygen. Colder water has a higher capacity (can "hold" more) for dissolved oxygen because the gas molecules in water are moving slower and are more compact. At higher temperatures, dissolved oxygen and other gases in water move faster and spread farther apart, including out of the water. Also at higher temperatures, the water molecules may move faster and bump out oxygen.
And what do you have against Asians, you 馬鹿外人?

Simple answer: hotter molecules move around faster than cold ones. So oxygen molecules dissolved in hot water will move out of solution faster than if the water were cold. This is why warm parts of oceans are pretty devoid of life but the colder parts are quite rich: more oxygen is dissolved in the water.
BTW, this is true for any gas dissolved in water.
