I think a burning and unattending candle is not safe because little kids can burn on the candle.
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.
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.
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.
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)
Burning a candle is considered a closed system because the wax and wick within the candle system are confined, and the energy and matter within the system (such as heat, light, and gases emitted) do not exchange with the surroundings. The energy released from burning the candle is contained within the system, making it a closed system.
the products of a burning candle are water vapor and carbon dioxide

A burning candle produces thermal energy and light.
a burning candle is a light source due to the fire.
A burning candle produces water vapor and carbon dioxide gas.
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.
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.
combustion is burning -_-
Burning the Candle - 1917 was released on: USA: 5 March 1917
An exothermic reaction involves the release of heat into a system. The burning of a candle is combustion reaction. Combustion reaction release heat, and this can be detected and measured by the burning of a candle's wax. From these testable observations it is determined fact that candle burning is indeed exothermic.
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.
If a candle has no oxygen, its flame goes out.
