CO2 can displace oxygen, because it is heavier than oxygen. Here is a link to nafed: "The mechanisms by which carbon dioxide extinguishes fire are rather well known. If we go back to the familiar fire triangle, we realize that an interaction between fuel, oxygen and heat is necessary to produce a fire condition. When these three elements are present in a proper relationship, fire will result. Carbon dioxide extinguishes fire by physically attacking all three points of the fire triangle. The primary attack is on the oxygen content of the atmosphere. The introduction of CO2 into the fire zone displaces sufficient oxygen in the atmosphere to extinguish the open burning. At the same time, the extinguishing process is aided by a reduction in the concentration of gasified fuel in the fire area. And finally, CO2 does provide some cooling in the fire zone to complete the extinguishing process.
What else can I help you with?
What are the two main gases?
Hydrogen and Nitrogen. Or oxygen and carbon dioxide, or carbon monoxide.
Which two gases make up 99 percent of the gases in the atmosphere which gas is more abundant?
I am looking for the exact same answer I know one of the gases should be oxygen
What are the two most abundant gases in the Earth?
The two most abundant gases in the Earth's atmosphere are nitrogen (about 78%) and oxygen (about 21%).
What are the 4 gases that make up earths atmosphere?
The four most abundant gases in Earth's atmosphere are nitrogen, oxygen, argon, and carbon dioxide. Nitrogen makes up about 78% of the atmosphere, oxygen around 21%, argon about 0.9%, and carbon dioxide less than 0.04%.
Does oxygen and nitrogen contain water?
No, oxygen and nitrogen are gases that do not contain water. Water is made up of two hydrogen atoms and one oxygen atom. Oxygen and nitrogen are elements that exist as gases in the Earth's atmosphere.
What are the semiconductor grade gases?
These gases apparently displace oxygen. E.G. nitrogen or argon
Which gases will replace oxygen in blood hemoglobin?
Carbon monoxide will replace, and displace, oxygen on hemoglobin. This is why carbon monoxide poisoning is so dangerous as the tissues slowly lose access to oxygen.
Can poisonous gases kill a human?
Yes. If you inhale enough of it to displace the oxygen content in your blood you can die from inhaling poisionous gasses.
Is nitrogen and argon injurious to health?
Although they are both inert gases and are not toxic, if there is enough of either gas in a confined space, they can displace oxygen. Without oxygen, humans become hypoxic and eventually die.
How do gases affect the body?
Gases can affect the body by entering the respiratory system and causing irritation or damage to the lungs. Inhaling certain gases can also displace oxygen in the bloodstream, leading to oxygen deprivation and potentially causing asphyxiation. Additionally, some gases can be toxic, leading to poisoning if inhaled in high concentrations.
What is the importance of knowing about heavy gases when entering a confined space?
Gases displace oxygen, and heavy gasses will sit under oxygen containing air, hence if you are in a confined space it is necessary to know about the potential lack of air supply to breathe, aswell as the potential of combustion and the like.
How can you lose oxygen?
You can lose oxygen by inhaling gases or substances that displace oxygen in the air, such as carbon monoxide or helium. Low oxygen levels can also result from living at high altitudes where the air is thinner. Additionally, oxygen levels can decrease in closed spaces without proper ventilation.
What gases will extinguish a burning splint?
Carbon dioxide (CO2) and nitrogen gas (N2) can extinguish a burning splint. These gases displace the oxygen in the air, which is necessary for combustion, and therefore extinguish the flame.
What are suffocating gasses?
Gases which are denser than normal air and which will sink to lower levels in an enclosed space. These gasses will displace the normal oxygen containing air. A leak of this type of gas within an enclosed room could end up suffocating anyone in the room, as the 'air' that they'd be breathing would not contain enough oxygen for them to survive.
Why is oxygen gas pumped in a small container?
Oxygen gas is pumped into a small container to displace any other gases present, creating an oxygen-rich environment. This can be useful for enhancing combustion processes, preserving perishable items, or supporting aerobic organisms that require oxygen to survive.
What is the toxicity of argon?
Argon is a noble gas and is generally considered non-toxic. It is chemically inert and does not react with other substances in the body. However, argon can displace oxygen in high concentrations, leading to asphyxiation in poorly ventilated spaces.
How does Argon displace oxygen- and moisture-containing air?
Argon is denser than air, so when it is introduced into a space, it sinks and pushes the oxygen- and moisture-containing air upwards and out. This displacement process occurs because of the differences in molecular weights of the gases.
