What else can I help you with?
Is black smoke from a candle a chemical change?
Yes, the black smoke from a candle is a result of a chemical change. It is the incomplete combustion of the wax in the candle, producing carbon particles that are visible as black smoke.
Why does a candle burn with a yellow flame?
Candle burns with a yellow flame because its an incomplete combustion. The temperature of the flame also relates to its colour and also the trace metal ions present will influence the flame colour.
Does candle light have a continuous light spectrum?
No, candle light does not have a continuous light spectrum. It produces a continuous spectrum with missing colors due to absorption by the flame and emission from soot particles, resulting in a warm, orange-yellow color.
Does water and candle wax form a solution or mixture?
Water and candle wax would not form a solution because they do not mix at a molecular level. Instead, they would form a mixture, where the candle wax would remain separate as droplets or particles within the water.
What is in a colored candle?
in a colored candle there is wax
What happens to the particles when a candle is burning?
The particles which are in a fixed position because the candle is a solid heat up and vibrate more this makes the candle expand
Where does the white smoke of candle come from?
The white smoke from a candle is caused by incomplete combustion of the candle wax, which releases tiny carbon particles in the air. These particles scatter light, making the smoke appear white. It is a normal occurrence when a candle burns.
Where does the smoke from a candle originated from?
The smoke from a candle originates from the incomplete combustion of the wax fuel. As the candle burns, the wax vaporizes and mixes with oxygen in the air. If the combustion is not efficient, it can produce smoke particles in the form of soot.
What is the identity of the smoke that is released when a candle is extinguished?
The smoke released when a candle is extinguished is primarily composed of unburned hydrocarbons and soot particles. These particles are the byproducts of incomplete combustion of the candle wax and wick materials.
Why can you relight a candle from the smoke?
When you relight a candle from the smoke, it is because the smoke contains unburned carbon particles that can reignite when exposed to a flame.
What statement describes the movement of the particles as the solid candle melts to a liquid?
As the solid candle melts to a liquid, the particles gain energy and move more quickly. This increased movement causes the particles to break away from their fixed positions in the solid structure, allowing them to flow and take on the shape of the container.
Is black smoke from a candle a chemical change?
Yes, the black smoke from a candle is a result of a chemical change. It is the incomplete combustion of the wax in the candle, producing carbon particles that are visible as black smoke.
Is the black soot produced when a candle is burned carbon?
Yes, the black soot produced when a candle is burned is mainly composed of carbon particles that have not completely combusted in the flame.
When burning a candle where does the smoke originate?
The wax and the wick burn, but not completely, the unburnt part being mainly carbon n the form of very small particles. These are quite hot and glow white, yellow, and red, and are resonsible for the 'flame' and its colour. After the particles leave the immediate area of the flame they cool down and don't glow any more. They are now the smoke.
Why does the candle relight when you put burning match near the smoke?
The smoke from the candle has vaporized wax, which is highly flammable vs carbon soot. When the flame touches the stream of vaporized wax (smoke) the heat is transferred back to the wick relighting it.
Why is candle wax an amorphous solid?
Candle wax is an amorphous solid because its particles are arranged randomly and do not have a specific crystalline structure. This lack of long-range order gives candle wax its characteristic properties of being soft and malleable at room temperature.
Why does a candle burn with a yellow flame?
Candle burns with a yellow flame because its an incomplete combustion. The temperature of the flame also relates to its colour and also the trace metal ions present will influence the flame colour.
