Our earth needs carbon dioxide because it is used in many amazing ways, from the air we breathe to the beer and construction industries.
This versatile gas also plays a crucial role in photosynthesis, helping plants produce the oxygen we rely on.
Beyond that, carbon dioxide is used in fire extinguishers, making it an unsung hero in safety and emergency situations. Below, we’ve outlined some of the most fascinating and significant Carbon Dioxide Facts.
Exploring Carbon Dioxide Facts
Dry Ice Does Not Dissolve
Dry ice, or frozen carbon dioxide, doesn’t dissolve. It sublimes under atmospheric pressure at 78.5 °C, instantly changing from solid to gas.
The air’s moisture condenses on the gas because it is so cold, producing a thick fog that is employed in stage and film effects. On chilly CO2 gas, moisture from the air condenses.
Temperature Effects of Co2
Earth’s lowest recorded natural temperature was 89.2 °C, measured in Antarctica in 1983.
As a side note, mercury would have solidified (m.pt = 38.8 °C), radon would have liquefied at this temperature, and carbon dioxide would have either fallen to the ground as snow or formed a mist of solid particles. (m.pt. −71 °C).
Snow Presence on Mars
Mars has experienced carbon dioxide snow; its atmosphere is 96% carbon dioxide and contains mainly argon and nitrogen.
Mars also has two polar ice caps that are present year-round. The ones on Mars are mostly made of water ice but also have a lot of carbon dioxide that has been frozen. At the poles of Mars, 25–30% of the atmosphere’s carbon dioxide is frozen.
Solid carbon dioxide sublimes during the spring thaw at a Martian pole, causing winds to reach speeds of up to 250 mph (400 km/h).
Spiked Drinks and Co2
The carbon dioxide that has been dissolved gives soda drinks, sparkling wines, and some beers their fizz.
The fizz manifests as bubbles when carbon dioxide leaves the solution and transitions back to the gas phase.
While it is typically intentionally added, carbon dioxide occurs naturally in some sparkling wines and beers.

Oceanic Liquid Carbon Dioxide
Carbon dioxide cannot exist as a liquid at atmospheric pressure, but it can at greater pressure. The pressure is almost 160 atmospheres at a depth of 1600 meters (one mile) beneath the ocean’s surface.
Champagne hydrothermal vent depth is where a stream that contains over 90% liquid carbon dioxide emerges.

Decaffeinated Coffee and Supercritical Fluid
Carbon dioxide can turn into a supercritical fluid at high pressures. In this condition, it resembles a mixture of a gas (it fills the container) and a liquid in that it is significantly denser than typical gases at atmospheric pressure and has solvent-like qualities.
Using the non-toxic supercritical carbon dioxide phase, as much as 99% of the caffeine in green coffee beans is removed, leaving behind the 1,000 or more compounds that give coffee its distinctive flavor and aroma.
In fact, supercritical carbon dioxide has more uses than any other material’s supercritical phase, including removing pesticides and poisons from crops and occasional usage as a solvent in dry cleaning.
Carbon Dioxide: The Vital Gas
Without carbon dioxide, neither green vegetation nor animal life would exist. Carbon dioxide and water are reacted by green plants using energy from the sun to create carbohydrates and oxygen.
Deadly Slumber: Life Giver and Life Taker
When yeast ferments sugar to produce alcohol, carbon dioxide is one of the byproducts. When cleaning fermentation vats from top hatches, workers died as a result.
Because carbon dioxide is denser than air, it keeps oxygen at bay and hides invisibly in the vats.
Due to lack of air, the cleaning crew members pass out before suffocating to death. Rescue attempts have occasionally ended in failure.
Importance of Trees for CO2 Absorption
The waste product of respiration is carbon dioxide. Every day, a single person exhales around 1 kg of carbon dioxide.
Two hundred fifty square meters of commercial conifer plantation in a moderate area can absorb this amount of carbon dioxide.
An average human exhales about 250 m of carbon dioxide absorbed by commercial plantations. A person who lives for 80 years will breathe out around 29 metric tons of carbon dioxide.
Using Co2 to Battle Fires
In particular, carbon dioxide fire extinguishers are advised against electrical fires since carbon dioxide does not cause electrical equipment damage like water does.
Carbon dioxide suppresses fire by depriving it of oxygen and chilling it.
Formation of Carbonic Acid
Water and carbon dioxide combine to form carbonic acid. Mollusks and corals create calcium carbonate, which they create by reacting calcium ions dissolved in ocean water with carbonic acid.
The skeletal remains of these creatures make up the majority of limestone and marble rocks.
To create seashells, mollusks use the carbon dioxide that has been dissolved in the oceans.
Earth’s Diameter Compared to Venus
Unfortunately, Venus is the wicked twin in life. The atmosphere’s 96.5 percent carbon dioxide at its surface exerts a crushing 92 Earth atmospheres of pressure.
In actuality, the atmosphere on Venus’ surface is a supercritical fluid.
The Greenhouse Effect
The runaway greenhouse effect brought on by the carbon dioxide has led to an average surface temperature of 465 °C, higher than any other planet in the solar system and far hotter than the hottest oven.
The surface of Mercury, which is the planet nearest to the sun, is cooler than Venus’.
On Venus, liquid forms of elements, including bismuth, cadmium, sulfur, lithium, tin, lead, and zinc, would exist. These substances are typically thought of as solids.
Naturally Occurring Co2 in The Atmosphere
Although carbon dioxide concentrations are so minute (about 0.04%) that monitoring is unnecessary everywhere, it is present in the air we breathe daily.
Yet, assessing carbon dioxide levels in an industrial setting is essential, particularly in confined spaces where levels can rise quickly without adequate ventilation.
Higher Co2 Levels in Crowded Rooms
Because we take in oxygen and exhale carbon dioxide, the amount of carbon dioxide in space can increase during the day. For precisely this reason, we’ve previously checked carbon dioxide levels at exhibitions!
You won’t be in danger despite the increase in carbon dioxide, but it can make you feel more exhausted and lethargic. The best course of action is to keep the space well-ventilated with lots of fresh air.
Co2: Tasteless, Colorless, and Odorless
It is difficult to detect a rise in carbon dioxide levels because it cannot be seen, tasted, or smelled. This is why keeping an eye on it is so crucial.
Carbon dioxide is possible to promote the growth of flowers, fruit, and vegetables.
The photosynthesis process, which plants use to produce food, involves sunlight, carbon dioxide, and water.
Although this is a delicate balancing act because if carbon dioxide levels are too high, it might harm the crops, greenhouse owners frequently raise the quantity of carbon dioxide in the atmosphere to promote growth.
Differences Between Carbon Dioxide and Carbon Monoxide
When you search for “carbon dioxide monitor,” many of the top results are for carbon monoxide, which is concerning. We’ve discovered that several people conflate carbon dioxide and carbon monoxide.
Carbon dioxide occurs naturally in the atmosphere, whereas carbon monoxide does not, even though both of these gases are tasteless and odorless.
Whereas carbon monoxide is lighter than air and accumulates higher up, carbon dioxide is heavier than air and accumulates closer to the ground.
Use of CO2 in Dispensing Beer
There’s a good possibility that a pub or bar you visit has a carbon dioxide meter in the basement or at the back of the building (or they should have one).
This is so because beer is pushed from the keg to your glass using carbon dioxide, often known as “dispense gas” or “bubble gas” in the beverage business.
Fires Can Be Extinguished with Carbon Dioxide
A few fire extinguishers use carbon dioxide. It takes away the oxygen that a fire needs to ignite and is affordable and easily accessible.
It can be risky, though, if utilized in a small area because it can deprive you and the environment of oxygen and the fire of oxygen.
