When ethyne is burnt in air, it gives a sooty flame. This is due to incomplete combustion caused by limited supply of air. However, if ethyne is burnt with oxygen, it gives a clean flame with temperature 3000°C because of complete combustion. This oxy-acetylene flame is used for welding. It is not possible to attain such a high temperature without mixing oxygen. This is the reason why a mixture of ethyne and air is not used.
Hope its fine with u !!
all the best !!

What is the difference between Ethane and EP Mix?
Ethane is a simple hydrocarbon compound consisting of two carbon atoms and six hydrogen atoms. EP Mix, on the other hand, is a blend of ethane and propane in varying ratios, typically used as a refrigerant in air conditioning and refrigeration systems. EP Mix offers a different boiling point range compared to pure ethane, making it suitable for different applications.
What are that 2 noble gases used to protect during welding?
The two noble gases commonly used to protect during welding are argon and helium. They are used to create an inert atmosphere that shields the molten metal from reacting with oxygen and nitrogen in the air, preventing oxidation and ensuring a strong, clean weld.
What is air-gas mixture?
It is a mixture of air with one or more other gases.
What effects do ethane have on the environment?
Ethane is a greenhouse gas that contributes to global warming when released into the atmosphere. It can also react with other pollutants to form ground-level ozone, which can harm human health and the environment. In high concentrations, ethane can contribute to air pollution and smog formation.
Is polluted air a substance or mixture?
mixture

What is the gas used in welding?
The most common gas used in welding is a mixture of argon and carbon dioxide, known as shielding gas. This gas helps protect the weld pool from contaminants in the air and stabilizes the arc during the welding process.
What type of welding machine use in spot welding or resistance welding?
Mainly In spot welding & resistance welding two type welding machines are used :- 1. Air Cooled & 2. water Cooled.
The electrode holder used for shielded metal-arc welding may not be used carbon arc welding?
Any electrode holder that will accommodate the size of rod can be used. Twin Carbon Arc Welding requires a specific holder. Air Carbon Arc Gouging requires a special holder that also supplies a stream of air.
What is a gas that starts with hel?
Ethane gas !
What are the breathable gases used in underwater welding?
Depends on the depth, generally we use regular compressed air down to about 170 fsw but if below 170 fsw we would use a gas mixture of heliox (helium and oxygen)
What happens to the argon gas when used in welding assuming it does not burn does it just dissipate into the air?
It just dissipates into the air.
What is the mass air flow sensor used for?
air/fuel mixture
Would air or argon have a higher density?
Argon has a higher density than air and is used in welding applications to displace air (oxygen) from the weld.
How air is form?
Air is a mixture of gases and can be used for many different things
Why is ethene and air not used for welding?
If your question is "Why is Acetylene and Oxygen used for welding/cutting NOT Oxygen and air"? This is why. Acetylene and air mixed in correct proportions produces a flame temperature of 4500F to 4800F degrees. Acetylene mixed with Oxygen in the correct proportions produces a flame well above 5500F degrees. This extra heat melts the metal faster and increases the speed you can cut or weld. Other gasses instead of Acetylene are used but do not produce as high a temperature. Oxygen is almost always used with these other gasses.
What are some examples of a gas gas solution?
One example of a gas dissolved in another gas is atmospheric air - oxygen and carbon dioxide dissolved in nitrogen. For gases the term mixture is more correct than solution.
