Specific weight of carbon dioxide and its density

Carbonic acid, or carbon dioxide, under natural conditions is in a gaseous state, has no odor or color, and tastes acidic. The content of carbon dioxide (CO₂) in the Earth's atmosphere is 0.03-0.04%, that is, from 0.3 to 0.4 ml per 1 liter of air. In liquid form, at normal atmospheric pressure, it does not exist, but passes directly from a solid state to a gaseous state. It is approximately one and a half times heavier than air. Under natural conditions, the density, or specific weight of carbon dioxide, is 1.977 kg/m³.

Carbon dioxide is an essential component of human life

The sources of carbonic acid, which in prehistoric times made up more than 80% of our planet's atmosphere, are putrefaction processes, volcanic emissions, combustion processes and oxidation. People and animals release carbon dioxide during breathing. Many people do not know this, but at night plants also release carbonic acid into the atmosphere.

CO₂ plays a fundamental role in the life of the entire planet and all its living beings. Its main “task” can be considered the maintenance of the photosynthesis process; it also participates in many metabolic processes of every living cell. It is not toxic and does not support breathing, although it plays a very important role in the breathing process itself.

Interestingly, in the blood of a fetus the amount of oxygen is 4 times lower than in an adult, while the amount of carbonic acid is 2 times higher. When the percentage ratio of oxygen increases, the embryo dies.

CO₂ is one of the necessary factors in maintaining the acid-base balance of blood and regulates enzyme activity in the body. For normal functioning of the human body, the amount of carbonic acid in the blood should be at the level of 7-7.5%; a decrease in this level to 4% threatens the death of the organism. Its deficiency activates the defense system: spasms of blood vessels and smooth muscles begin, the amount of mucus in the respiratory tract increases, more cholesterol is formed, as a result of which cell membranes become denser and prevent the transport of substances. All this leads to deep oxygen starvation (according to the Bohr effect).

Thus, according to scientific research, CO₂ is indispensable for:

• breathing,
• metabolism,
• regulation of internal hormonal processes,
• stimulation of the respiratory center,
• calming the nervous system,
• dilation of blood vessels.

CO₂ is necessary for animals

The cycle of substances in nature ensures a relatively stable level of carbonic acid in the atmosphere. When keeping animals, it is extremely important to maintain the natural level of CO₂ indoors. Proper cleanliness, ventilation and correct placement of animals solve the problem of air oversaturation with carbon dioxide. Recall that its normal content is 0.3-0.4 ml per 1 liter of air. If animal housing conditions are not followed, the amount of carbonic acid can increase to 1% or more.

For example, a horse releases about 130 l of CO₂ per hour, a cow - up to 200 l, sheep - up to 30 l, and pigs - up to 90 l. If the concentration of carbon dioxide in an enclosed room exceeds 0.5%, this will negatively affect the vital activity of the organism: poisoning occurs, productivity and immunity decrease, lethargy, apathy and loss of appetite appear, and animals lose weight.

Carbonic acid is vital for all living organisms on our planet. If it disappears, all living things will die, but if there is too much of it, the result will be the same.
