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.
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 can provide fuel for the flame, allowing the candle to burn. It also helps to shape and hold the wick in place. Additionally, certain types of candle waxes can impact factors such as burn time, scent throw, and appearance of the candle.
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.
There are multiple physical changes and chemical changes that occur when a candle burns. One physical change is that the candle melts back into liquid wax. One chemical change is flame burning on the wick.
The fuel for a burning candle is wax, which is a hydrocarbon. When the candle burns, the wax is converted into carbon dioxide and water vapor through a combustion reaction. This process releases energy in the form of heat and light.
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 typically reacts with oxygen in the air when it is burning, producing heat, light, and carbon dioxide. The chemical reaction that occurs during the burning of candle wax is called combustion.

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.
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.
Normally the part closest to the flame (the wax).

The wick. The wax is there to prevent the wick from burning too fast.
The fuel for a burning candle is wax, which is a hydrocarbon. When the candle burns, the wax is converted into carbon dioxide and water vapor through a combustion reaction. This process releases energy in the form of heat and light.
The burning of candle wax releases energy in the form of heat and light. This is due to the chemical reaction of the wax (hydrocarbons) with oxygen in the air, producing carbon dioxide and water vapor as byproducts.
