Is burning a candle wick a physical property?
No, burning a candle wick is a chemical change, not a physical property. Physical properties describe characteristics that can be observed without changing the substance's identity, while chemical changes involve the rearrangement of atoms and result in a new substance being formed.
What type of reaction occurs when a candle is burned?
The burning of a candle is a chemical reaction called combustion, which involves the candle wax (a hydrocarbon) reacting with oxygen in the air to produce carbon dioxide, water vapor, and heat. This reaction releases energy in the form of light and heat.
Is burning of paper is one example of physical change?
Burning of paper is actually an example of a chemical change, not a physical change. During burning, the chemical composition of the paper changes as it reacts with oxygen to produce new substances like ash, water vapor, and carbon dioxide.
When a candle burns both physical and chemical changes take place Identify these changes?
the physical change is -the shape of the candle changes,some of the wax becomes liquid to solid. chemical change-the wick is burned *Hi just wanted to say that this person above is wrong...I mean, the wick burning would be a chemical change because it is combustion. They are wrong because the wick doesn't actually burn.The wax is absorbed by the wick which cools it off. Eventually the wick becomes too long and the top of it dries out and falls off into the wax. Fact being, the wax vapor burns. You should do some more individual research for details because there is more. Thanks!
Which one is not a physical change?
the physical change is the change that you can not hear see or fell. ex she cut her hair, or your heart is beating faster.
Is a candle burning a physical change?
It is actually both. The burning of the wick involves a chemical change. The physical change is the wax.
What part of a burning candle takes place and physical change?
The melting of the wax is a physical change. The burning the of wick is the chemical change
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.
Is candle burning physical change?
Physical change means change physically while chemical change means change chemically or change in chemical properties.Like if you would drop a chip of zinc in sulphuric acid it will its color will be changed which is no doubt a physical change.But,also its properties are changed as it will be transformed into zinc sulphate from simple zinc,thus it also undergoes a chemical change. Now,with your question,the candle breaks but the candle remains the candle,so,its not a chemical change but a physical change only.Hope it helps!
How does a burning candle show both of chemical and physical change?
because it can
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.
Why is the burning of a candle a physical change?
The wax melts, it can solidify into a solid again.
What are the steps to prove that a burning of a candle is physical as well as a chemical change?
To prove that the burning of a candle is a physical and chemical change, you can observe the physical changes such as the melting of the wax and the formation of soot. Additionally, you can analyze the chemical changes by noting the production of carbon dioxide and water vapor during the combustion process. By observing both physical and chemical changes, you can demonstrate that burning a candle involves both types of transformations.
What a the physical properties of the wax in a burning candle?
Wax will melt and is converted from solid to liquid. It is a physical change.
What are the physical properties of the wax in the burning candle?
Wax will melt and is converted from solid to liquid. It is a physical change.
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.
Is candle wax burning a physical change?
For the wax, yes. It changes to a liquid and then back to a solid. But some of the wax is also consumed in a chemical change as it oxidizes, along with the burning wick.
