How is energy released from gasoline during combustion?

Energy is released from gasoline during combustion through a chemical reaction in which bonds in the gasoline molecules are broken and new bonds are formed in the products of combustion, primarily carbon dioxide and water. This process is an example of an exothermic reaction, where the total energy of the products is lower than that of the reactants, resulting in the release of energy, primarily in the form of heat.

In gasoline, the hydrocarbons are made up of carbon and hydrogen atoms held together by chemical bonds. During combustion, these bonds are broken, and energy is required to do this. Once the bonds in the reactants (gasoline and oxygen) are broken, new bonds form as the products of combustion are created. The formation of these new bonds releases energy because the products are more stable than the reactants. The difference in energy between the reactants and products is released, which is what we perceive as heat and light during the combustion process.

The other options do not accurately describe the main process of energy release in combustion. Evaporation refers to a physical change, not a chemical one. Light is a byproduct of combustion, but it is not the primary way energy is released. Solid residue can occur in some cases, such as in inefficient combustion
