Chemical compounds, like oil or coal, hold potential chemical energy in the powerful molecular bonds with the compound. If such a chemical compound undergoes a chemical reaction (in this case in an internal combustion engine), the potential chemical energy will be released in the form of thermal energy. Of course, no energy transformation is 100% efficient as some of the potential chemical energy is either not converted at all or converted into a different form of energy. Take the example of a fire in one's fire place. Although a large percentage of the potential chemical energy in the wood is converted into thermal energy that we can feel as heat, some of the energy is converted into light, that we can see as the brightness of the fire, and some is converted into sounds, as we can hear in the roaring of the fire.

What converts chemical energy to thermal energy?

When chemical bonds are broken in a chemical reaction, the energy stored in those bonds is released as thermal energy, leading to an increase in temperature. This process involves the conversion of chemical energy into heat.


What is an example of chemical energy transforms into thermal energy?

An example of chemical energy transforming into thermal energy is when gas or wood is burned in a fire. The chemical energy stored in the gas or wood molecules is released as heat and light energy during combustion, creating thermal energy in the form of fire.


What is the chemical energy characteristics?

Chemical energy is a form of potential energy stored in the bonds of chemical compounds. It is released when these bonds are broken in a chemical reaction. Chemical energy can be converted into other forms of energy, such as thermal or mechanical energy.


A substance whose potential chemical energy is transformed into thermal energy is called a?

A substance whose potential chemical energy is transformed into thermal energy is called a fuel. When the fuel undergoes combustion or a chemical reaction, its stored energy is released in the form of heat.


What is the energy flow diagram of a burning candle?

When a candle burns, the energy flow diagram shows chemical energy from the wax being converted to heat and light energy through combustion. The chemical potential energy stored in the wax molecules is released as heat and light when the wax reacts with oxygen in the air. Some energy is also lost to the surroundings as thermal energy.
