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.

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.


Is a burning candle potential or kenetic energy?

A burning candle represents both potential and kinetic energy. The potential energy is stored in the candle wax and is released as heat and light energy when the candle burns, which is the kinetic energy produced.


What forms of energy are transferred by a burning candle?

A burning candle transfers energy primarily in the form of heat and light. The chemical energy stored in the candle wax is converted to heat and light energy through the process of combustion.


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.


How can you explain the physical change of a burning candle using the big idea of energy?

The physical change of a burning candle can be explained using the big idea of energy by understanding that the burning process releases stored chemical energy in the wax as heat and light energy. The chemical bonds in the wax molecules break, converting chemical energy into thermal and electromagnetic energy. This change is an example of the conservation of energy principle, where energy is transformed from one form to another but not created or destroyed.


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.


How can you change the burning time of a candle?

It can be changes by changing the size or the thickness of the candle, or changing the nature of the wax.


How do you know that the burning of candle of wax is an exothermic change?

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.


What are the physical properties of the wax in the burning candle?
