Why is it that when the air and water shine together, there is no red in the water?

For the mirrors in the air are white, and the mirrors in the water are black.

Of course!

First, there are bubbles when the water is heated, which means that there is gas in the water, and when the temperature is high, the solubility of the gas decreases, and the gas cannot be dissolved in it, so it will escape.

Second, the fact that fish and plants can survive in the water also means that there are certain gases dissolved in the water. Electrolytes do not indicate the presence of gas in water.

Water is produced when basalt first melts and then cools to form the original crust. Originally, the Earth was an icy sphere. After that, radioactive elements such as uranium and thorium present in the earth's interior begin to decay and release heat energy.

As a result, the material in the interior of the earth also began to melt, the substances with a high melting point sank, and the meltable substances rose, from which the volatile substances were separated: nitrogen, oxygen, carbohydrates, sulfur and a large amount of water vapor, and experiments proved that when 1 m3 granite melts, 26 l of water and many completely volatile compounds can be released.

When we talk about air, it is about 20% oxygen, about 80% nitrogen, and a very small amount of other gases.

From the above definition of air, there is no air in water.

But water dissolves or absorbs gases from the atmosphere, including oxygen, nitrogen, carbon dioxide, argon, helium, and so on. In some water bodies enriched with organic matter, reducing agent gases such as methane, hydrogen, and hydrogen sulfide are often present.

At 0, each liter of water contains:

Hydrogen liters, oxygen liters, carbon dioxide liters;

At 20 hours, each liter of water contains:

Hydrogen liters, oxygen liters, carbon dioxide liters;

Many animals, such as fish in the water, breathe in the water through their gills.

In a sense, there is some air in the water. Otherwise, how can the fish live?

No, the normal air is 80 nitrogen, 16 oxygen, 4% other gases, only oxygen can be dissolved in water, not air, because air is a mixture of gases, and oxygen is dissolved in water, not air.

Of course! Proof: First, there are bubbles when the water is heated, which means that there is gas in the water, and when the temperature is high, the solubility of the gas decreases, and the gas cannot be dissolved in it, so it will escape.

Second, the fact that fish and plants can survive in the water also means that there are certain gases dissolved in the water. Electrolytes do not indicate the presence of gas in water.

There is air in the water. All living things are inseparable from air. Like fish living in water, they also need to breathe, they use their gills to filter out the air in the water, use it for their own use, and then remove the water. Some gases will be dissolved in the water.

As for atmospheric pressure, everything on Earth is subject to atmospheric pressure, and we don't feel it because we're used to it. Atmospheric pressure on water. So much so that water cannot automatically fly into the air. The atmospheric pressure in the water is not very weak either. Because the water itself collects atmospheric pressure.

Of course there is air, how can fish survive without air.
