Does a blue flame require less air or more?
A blue flame typically requires more air because it indicates complete combustion of the fuel, resulting in a clean and efficient burn. The presence of excess oxygen is what creates the blue color in the flame.
What make gas flame luminous?
A luminous gas flame appears yellow or orange due to incomplete combustion, which produces soot particles that emit light when heated. The mixture of fuel and air in the flame is not perfectly balanced, leading to an excess of fuel that results in the incomplete combustion process.
The bottom of a test tube was covered with soot after an experiment which required heating. What kind of flame was used during the experiment?
A yellow, smoky flame was likely used during the experiment, which produced soot as a byproduct of incomplete combustion. This type of flame is often seen with a fuel-rich mixture or inefficient burning of the fuel.
What is the sound produced luminous flame?
A luminous flame produces a crackling or roaring sound due to the rapid combustion of fuel. The sound is caused by the release of energy as the flame burns, creating vibrations in the surrounding air. The intensity of the sound can vary depending on the type of fuel and the conditions of combustion.
What is the luminosity of a flame?
The luminosity of a flame is the amount of visible light it emits. It varies depending on factors such as the type of fuel being burned, the temperature of the flame, and the presence of impurities. Flames with higher luminosity appear brighter.
Is candel wax a type of fuel?
Yes, candle wax is a type of fuel. When a candle is lit, the heat of the flame melts the wax, which is then drawn up the wick and vaporized, providing fuel for the flame.
Why cant a candle burn with a roaring flame?
A roaring flame requires a continuous supply of fuel and air. In the case of a candle, the size and composition of the wick limit how much fuel can be drawn up to the flame. If the wick is too large, it may produce excess soot and smoke instead of a stable flame.
How does the fuel get to the flame?
by the wick the fuel gets to the flame
Why is a blue flame called a clean flame?
A blue flame is called a clean flame because it indicates complete combustion of the fuel, resulting in minimal production of soot and pollutants. The blue color is due to the high temperature of the flame, which signifies efficient burning without excess unburned fuel. This makes a blue flame more environmentally friendly compared to a yellow or orange flame.
What do you see when a fuel is burning?
When fuel is burning, you typically see a flame producing light and heat as a result of the chemical reaction between the fuel and oxygen. The color and intensity of the flame can vary depending on the type of fuel being burned.
What type of energy is a flame?
A flame is a form of thermal energy that results from the combustion of a fuel source. Heat and light are produced when the fuel undergoes rapid oxidation in the presence of oxygen.
Does a blue flame require less air or more?
A blue flame typically requires more air because it indicates complete combustion of the fuel, resulting in a clean and efficient burn. The presence of excess oxygen is what creates the blue color in the flame.
Which type of flame should you use when you are temporarily not heating anything?
When you are temporarily not heating anything, you should use a safety flame or a low flame. This type of flame is small and controlled, reducing the risk of accidents and conserving fuel. It provides enough visibility to work safely without the intensity of a higher flame.
What causes a burner flame to be smoky and to separate from the tip of the burner?
A smoky burner flame that separates from the tip of the burner is typically caused by an incorrect air-to-fuel ratio. This can be due to a clogged burner or inadequate airflow. It can also be caused by a lack of proper maintenance or adjustment of the burner.
What are the factors influence flame height?
Factors that influence flame height include the amount of fuel being burned, the rate at which it is being burned, the presence of oxygen for combustion, and environmental conditions such as wind speed and direction. Additionally, the type of fuel being burned and the shape and size of the flame source can also impact flame height.
What kind of flame is a yellow flame called?
A yellow flame is typically called a reducing flame. This type of flame is often seen in gas stoves and burners where there is an imbalance of air and fuel, leading to incomplete combustion and producing a yellow color.
What make gas flame luminous?
A luminous gas flame appears yellow or orange due to incomplete combustion, which produces soot particles that emit light when heated. The mixture of fuel and air in the flame is not perfectly balanced, leading to an excess of fuel that results in the incomplete combustion process.
