coal is naturally available and is carbon based.Coal is a combustible black or brownish-black sedimentary rock normally occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. Coal is composed primarily of carbon along with variable quantities of other elements, chiefly hydrogen, with smaller quantities of sulfur, oxygen and nitrogen.
Coal is primarily used as a solid fuel to produce electricity and heat through combustion
candle is made of wax.A candle is a solid block of fuel (commonly Solid wax) and an embedded wick, which is lit to provide light, and sometimes heat.
Today, most candles are made from paraffin. Candles can also be made from beeswax, soy, other plant waxes, and tallow (a by-product of beef-fat rendering). Gel candles are made from a mixture of paraffin and plastic.
The burning of the fuel takes place in several distinct regions (as evidenced by the various colors that can be seen within the candle's flame). Within the bluer regions, hydrogen is being separated from the fuel and burned to form water vapor. The brighter, yellower part of the flame is the remaining carbon being oxidized to form carbon dioxide.[citation needed]
As the mass of solid fuel is melted and consumed, the candle grows shorter. Portions of the wick that are not emitting vaporized fuel are consumed in the flame. The incineration of the wick limits the exposed length of the wick, thus maintaining a constant burning temperature and rate of fuel consumption.
What else can I help you with?
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)
Can burning a candle be reversible?
No, burning a candle is not reversible. When a candle is burned, the wax is melted and the wick is consumed, resulting in irreversible changes to the candle's structure.
Which process is similar to a burning candle except for the difference in temperature?
Sublimation is a process similar to a burning candle but occurs at a lower temperature. It involves a substance transitioning directly from a solid to a gas without passing through the liquid phase.
Why does candle wax evaporate when the candle is burning?
Candle wax evaporates when the candle is burning because the heat from the flame causes the wax to melt and turn into a gas, which then evaporates into the air.
What happens to burning candle if there is no oxygen?
If there is no oxygen, a burning candle will not be able to sustain the combustion process since oxygen is needed for the flame to continue burning. The candle will eventually go out in the absence of oxygen.
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.

What is the difference between a goldfish and the flame of a burning candle?
the goldfish is a living thing
Why does burning of candle produce flames and burning of coal cannot?
First of all we will have to know that what is a flame made up of,a flame is made at a point where fuel and oxygen combine,so in case of both candle and coal there is a fuel ie.wax in candle and coal is itself a fuel.................but if we just think till this much then even coal should produce flame but it doesn't go like this ,actually we are missing something ie. hydrogen(the main component in every flame producing substance).........if hydrogen is not there flame will not be produced .So wax has hydrogen atoms whereas coal doesn't because coal has been burnt before and hydrogen has been used.................that is why hydrogen containing waxy candle produces flames whereas already burnt coal just gives heat not flames. Hope this helps.
When a candle is burning what are the products burning?
the products of a burning candle are water vapor and carbon dioxide
Can burning a candle be reversible?
No, burning a candle is not reversible. When a candle is burned, the wax is melted and the wick is consumed, resulting in irreversible changes to the candle's structure.
A burning candle is what kind of energy?
A burning candle produces thermal energy and light.
Is a burning candle a light sources?
a burning candle is a light source due to the fire.
What is the product of a burning candle be?
A burning candle produces water vapor and carbon dioxide gas.

Is burning a candle an example of combustion?
combustion is burning -_-
