How can a science project be designed to explore methods of relighting a candle without physical contact?
To explore methods of relighting a candle without physical contact, a science project can be designed by setting up different experiments using various techniques such as using a laser, sound waves, or magnetic fields to relight the candle. The project should include a control group where the candle is relit using traditional methods for comparison. Data should be collected and analyzed to determine the most effective method for relighting the candle without physical contact.
Why does a lit up candle emit smoke?
A lit candle emits smoke because as the wax heats up and vaporizes, it combines with oxygen in the air to form carbon dioxide and water vapor. Incomplete combustion of the wax can also result in the production of carbon particles, which appear as smoke.
Why is the light bulb safer than the candle?
Candles are able to start fires more easily than are light bulbs, although high wattage light bulbs are able to start fires as well. A smaller concern but a concern nonetheless is that burning candles consumes oxygen, and a light bulb does not. Also in a dark room a candle might unexpectedly go out, causing a safety concern in attempting to relight the candle in the dark.
Why does smoke rise rather then fall from a lighted candle?
floating candles float higher in the water a they burn because as the candle burns it is decreasing its mass and deplacing less water, so it floats higher....but im not sure? its burning off the wax and makes the candle more buoyant which means it just burns off weigh... sorry for answering so late... enjoy
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 is the hardest candle to blow out?
A trick birthday candle, also known as a magic candle or a never-ending candle, is designed to relight itself after being blown out. It can be challenging to extinguish because it surprises the person trying to blow it out.
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.
How did Joseph Priestly relight the candle in his experiment?
Joseph Priestley relit the candle by placing a mint leaf near the flame, which resulted in the flame rekindling due to the release of oxygen from the mint leaf during photosynthesis. This experiment demonstrated the concept of oxygen being necessary for combustion.
What does a candle let out?
A candle when it burns lets out smoke.
What are the release dates for Candle Smoke - 1998?
Candle Smoke - 1998 was released on: USA: September 1998
Can you relight a Black And Mild?
Yes but it will be harsh and most likely unpleasant to smoke.
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.
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.
When does smoke come from a candle?
when the fire goes out.
What is the smoke that comes out of a candle called?
Carbon
