How is a burning candle both physical and chemical changes?
A burning candle involves both physical and chemical changes. The physical change is the melting of the wax, while the chemical change is the wax combining with oxygen in the air to produce heat, light, carbon dioxide, and water vapor.
What is Orange when hot and yellow when cold?
It's a candle. When the wax is hot and melting, it appears orange, while when it cools and solidifies, it turns yellow.
What is the difference between boiling and burning?
Oh, dude, boiling is when you heat up a liquid until it reaches its boiling point and turns into vapor. Burning is when you set something on fire and it undergoes a chemical reaction to produce heat and light. So, like, one turns into steam and the other turns into ash. Easy peasy.
What chemical reactions occur during burning a candle?
During the burning of a candle, the wax (hydrocarbons) undergoes a combustion reaction with oxygen from the air. This reaction produces carbon dioxide, water vapor, heat, and light. The heat melts and vaporizes the wax, while the light comes from the glowing soot particles that are formed during incomplete combustion.
Why are there several colors in candle flames?
Candle flames have different colors due to the different elements present in the burning process. The blue part of the flame is from combustion of carbon and hydrogen, while the yellow part is due to soot particles emitting light when heated. The colors can also be influenced by impurities and additives in the candle wax.
Why the the mass of a candle does not disappear while burning?
Because of the law of conversation of mass
What does it mean when you are burning a candle for someone and the wick has some kind of green residue on it while burning?
Green residue on the wick could indicate that the candle contains impurities or additives that are burning off. It could also be a sign of the candle burning unevenly, which may be caused by the wick being too long or the candle being exposed to drafts. It's best to trim the wick and avoid burning the candle in a drafty area to prevent this issue.
Explain why the mass of a candle does not disappear while burning?
Because of the law of conversation of mass
What type of physical change will while crushing a rock and burning a candle?
1. Crushing is a physical process.2. Burning is a chemical process.
How is a burning candle both physical and chemical changes?
A burning candle involves both physical and chemical changes. The physical change is the melting of the wax, while the chemical change is the wax combining with oxygen in the air to produce heat, light, carbon dioxide, and water vapor.
What kind energy does a burning candle elicit?
chemical
Crushing a rock creates a physical change while burning a candle creates this type of change?
jhn
How does a candle produce carbon dioxide while it burns?
Any burning (oxidation reaction) produce carbon dioxide.
Why is melting of covered candle a physical change while burning of a candle wick a chemical change?
This is because a candle will change its whole form and stay that way, which is a physical outer change. And a candle wick only burns, it doesn't change it's appearance.
If the gases released by a burning candle could be contained and measured would you see that their mass is the same as the candle's was before it was lit and what law does this example describe?
This experiment is a verification of the law of the conservation of matter. And yes, the mass of all the combustion products would be equal to the mass of the candle and the oxygen it consumed while burning.
What two forms of energy does the fire from burning candle release?
The fire from a burning candle releases both heat energy and light energy. Heat energy is generated by the combustion of the candle wax and fueling the flame, while light energy is emitted as visible light when the carbon particles in the flame are heated to incandescence.
What is the use of a Candle holder?
to hold candles -.- To hold and support candles while they are burning so that they don't tip over.
