Answer: Chemical energy changes to light and heat energy.
Explanation:
The energy that is found in the wooden log is the chemical energy which is found in the bonds of carbon.
When the wooden log is burnt, the bonds are broken and the energy is converted in the form of light and heat. This is the conversion of chemical energy into heat energy and light energy.
This is also known as combustion in which a hydrocarbon is burnt to produce light and heat and carbon dioxide is released during the process.
When the form of the energy changes to produce the product then is called energy transformation. The burning of the log is the conversion of chemicals to heat and light energy.
Energy transformation is the conversion of one state of energy into another during the reactions. Energies can be in the form of chemical, electrical, mechanical, heat and light and sound.
In the wooden log, the chemical energy is present initially as they are made up of carbon, hydrogen, oxygen and other elements that are chemicals. When the log is burned than the chemical bonds are broken.
The broken bonds of the elements convert the chemical energy in the form of light and heat. The burning of logs is a combustion reaction that results in heat production along with the products.
Therefore, option B. chemical energy converts into heat and light.
