Why is a candle melting a chemical change?
Melting is accompanied by burning and thermal degradation - two chemical reactions.
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
Is burning of a candle a periodic change?
Yes, the burning of a candle is a periodic change because it involves the repeated process of the wax melting, being drawn up the wick, and then being burnt, which occurs in a cyclical manner as long as the candle is lit.
What are the 53 observations that Michael Faraday observed from a lit candle?
Michael Faraday observed 53 observations from a lit candle, including the melting of the candle, the formation of a pool of melted wax around the wick, and the chemical changes involved in the burning process. He also noted the role of air in sustaining combustion and the composition of the products of the candle's burning.
Is it a physical change when a candle changes size by burning?
Oh, dude, yes, it's totally a physical change when a candle burns and changes size. The wax is melting and then solidifying again as it cools down, so it's like a hot and cold dance party for the molecules. It's not like the candle magically grows or shrinks, it's just physics doing its thing.
What name is given to a process such as a burning a candle?
melting and burning
What is the difference between melting of candle wax and burning of candle?
Burning a candle is the process in which the wick is burnt. The wax is there to make the wick burn slower in order to let the candle burn for longer. Melting wax is part of the process but not burning the candle itself.
Does color affect a candles melting?
No, the color of a candle does not affect its melting point. The melting point of a candle is determined by the type and quality of wax used, not by its color.
Do colred candles melt faster than white candles?
Candle color does not typically affect how fast a candle melts. The melting rate of a candle is more dependent on factors like the type of wax, wick size, and burning conditions. However, some fragrances or dyes in colored candles may affect burning time and intensity.
Why is a candle melting a chemical change?
Melting is accompanied by burning and thermal degradation - two chemical reactions.
Is a wick necesarry in a burning candle?
Yes that is what burns the melting wax prolongs the burning time by slowly evaporating
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 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
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 a candle a periodic change?
Yes, the burning of a candle is a periodic change because it involves the repeated process of the wax melting, being drawn up the wick, and then being burnt, which occurs in a cyclical manner as long as the candle is lit.
Does the color of a candle affect the burning rate?
the color has nothing to do with the candle at diffrent burning rate it is the wick. We found that color does make a difference. We bought the exact same candles except each candle was a different color. Found out that the white candle burned down the fastest, the red was next, and so on. So candle wax color does make a difference in the burning rate of a candle. ( My daughter had a science experiment)
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.
