What is minimum concentration of oxygen required for combustion?
The minimum concentration of oxygen required for combustion is typically around 16% in air. Below this level, the fuel will not be able to sustain a flame or combust.
What types of flame are obtained in oxy-acetylene gas welding?
When the correct amount of Oxygen is mixed with the Acetylene a NEUTRAL flame is produced. Less than that amount produces a CARBURIZING flame. Too much Oxygen creates an OXIDIZING flame. Most welding/cutting is done with a NEUTRAL flame but all flame adjustments have their purpose.
What color does sulfur turn a flame with oxygen?
Sulfur burns with a blue flame when it reacts with oxygen.
What colour flame is copper when burned with oxygen?
Copper burns with a green flame when ignited with oxygen.
What is the colour of the flame when barium burns with oxygen?
The flame color of barium burning in oxygen is green.
What gas is required to keep the flame of a candle glowing?
OXYGEN
What type of gas does fire need?
Oxygen is required in order for a fire to continue burning. Without oxygen a flame will extinquish itself.
What is minimum concentration of oxygen required for combustion?
The minimum concentration of oxygen required for combustion is typically around 16% in air. Below this level, the fuel will not be able to sustain a flame or combust.
How is fabric flame retardant?
flame needs oxygen in order to keep on burning. fabric might cut that source of oxygen and the fire might go out, but there is a limit to how much flame a fabric can put out I think...

How much oxygen goes into a Bunsen burner when the flame is yellow?
Little/none
What gas bursts into flame when it reaches oxygen?
air will burst into flame in pure oxygen
Why does the flame of a candle die when you cut off air supply?
The flame of a candle requires oxygen to continue burning. When you cut off the air supply, the flame is deprived of oxygen which is essential for the combustion process. Without oxygen, the flame cannot sustain itself and eventually dies out.
What is the colour of the flame when barium burns with oxygen?
The flame color of barium burning in oxygen is green.
What colour flame is copper when burned with oxygen?
Copper burns with a green flame when ignited with oxygen.
What are the three types of acetylene welding flames?
Mixing Acetylene and Oxygen in the correct proportions produces an extremely hot flame. Using just enough Oxygen so that the Acetylene is almost completely consumed in the flame is called a Neutral Flame. In most welding and cutting applications you would utilize this flame. Reducing the amount of Oxygen produces a Carburizing Flame. It is yellowish and not as hot as a Neutral Flame, but, is used in certain situations. Welding Aluminum is one. Increasing the Oxygen produces an Oxidizing Flame. It produces a flame that is pointed, colder, and louder than a Neutral Flame. It wastes fuel and isn't as efficient as a Neutral Flame.
