How is air dissolved in water different from ordinary?

So, water contains CO2 gas more than nitrogen and oxygen gases. As a result, air dissolved in water contains CO2 gas in greater amount and nitrogen, oxygen gases in lesser amount while ordinary air contains nitrogen ,oxygen gases in greater amount and CO2 in lesser amount.

Q. Where does the water Vapour come from in air?

Under normal circumstances, water vapor enters the atmosphere through evaporation and leaves by condensation (rain, snow, etc.). Water vapor also enters the atmosphere by a process called sublimation. That occurs when water vapor moves into the air directly from ice without first becoming water.

Q. Does air have water Vapour?

Air does contain water in the vapor (gaseous) state even though you cannot see it until it condenses.

Q. Does water dissolve in air?

Water vapor is not dissolved in air. Imagine a closed container containing a beaker of pure water and a beaker of ocean water. Place the two solutions side by side so that they are at the same atmospheric temperature and pressure. The air above these two solutions is at the same temperature and pressure.

Q. How will u show that air is dissolved in water?

Take some water in a glass or metal container like pan and heat it. Just before water begins to boil, you will notice some bubbles at the inner surface of the pan. These bubbles come from the air dissolved in water. This shows that air is dissolved in water.

Q. Is water vapor pure?

Thus, liquid water, a mixture of liquid water and water vapor, and a mixture of ice and liquid water are all pure substances; every phase has the same chemical composition.
