What cause the luminousity of the flame?
The color of the flame depends on the temperature, fuel nature, composition of particles in the flame, oxygen concentration.
What flame type has excess fuel?
A yellow flame typically indicates excess fuel in combustion. This happens when there's an incomplete burning of the fuel, leading to the presence of unburned fuel molecules that emit a yellow color.
When does the flame of a Bunsen burner becomes small or big?
The flame of a Bunsen burner becomes small when the air inlet is closed, leading to a fuel-rich environment. It becomes bigger when the air inlet is opened, allowing more oxygen to mix with the fuel gas and create a hotter, larger flame.
What the center of a flame is called?
The center of a flame is called the "inner cone." It is the hottest part of the flame and appears blue in color due to the complete combustion of the fuel.
What happen to the color of the flame when powdered charcoal was sprayed on it?
When powdered charcoal is sprayed onto a flame, the color of the flame may turn a bright orange or yellow due to the carbon particles burning and emitting light. The charcoal acts as a fuel source, enhancing the combustion process and intensifying the color of the flame.
What cause the luminousity of the flame?
The color of the flame depends on the temperature, fuel nature, composition of particles in the flame, oxygen concentration.
Spectral properties of a flame?
The spectral properties of a flame refer to the visible light emitted when a hydrocarbon fuel burns. The color of the flame can indicate the temperature and the presence of certain elements in the fuel. Spectral analysis of the light emitted from a flame can be used to identify the chemical composition of the burning material.
What is the chemical composition of a flame?
A flame is pure energy so it has no real chemical composition except from the chemical compositions of the oxygen and fuel (usually hydrocarbons) needed for it to burn. A flame requires fuel, oxygen and heat energy, although it gives off light and heat energy as well. The act of burning is reacting the fuel with oxygen in the air but the flame itself has no chemical composition.
What happens to the color of the flame if you spray charcoal in the non luminous flame?
Sprinkling charcoal powder into a non-luminous flame will not change the color of the flame. The flame color is determined by the elements present in the fuel being burned, not by adding additional substances like charcoal.
What are two factors that affect the ignitability of a solid fuel?
The two main factors that affect the ignitability of a solid fuel are the fuel's composition and moisture content. The composition of the fuel determines its chemical properties and reactivity, while moisture content can affect the fuel's ability to burn by interfering with the combustion process.
What flame type has excess fuel?
A yellow flame typically indicates excess fuel in combustion. This happens when there's an incomplete burning of the fuel, leading to the presence of unburned fuel molecules that emit a yellow color.

What the center of a flame is called?
The center of a flame is called the "inner cone." It is the hottest part of the flame and appears blue in color due to the complete combustion of the fuel.
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.
Why the dominant color of the flame of a properly adjusted burner is blue?
The blue color of the flame indicates complete combustion of the fuel. This means that there is enough oxygen present for the fuel to burn efficiently, resulting in a clean and hot flame. Incomplete combustion often produces a yellow or orange flame due to the presence of unburned particles in the exhaust.
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.
What color flame burns the hottest?
Its not a Blue Flame (blue flame)its a white flame. i believe it can get around 1,000degrees
