Gasoline is a form of chemical energy. It consists of hydrocarbons, which are molecules made up of hydrogen and carbon atoms. When gasoline burns in an engine, a combustion reaction occurs, releasing energy in the form of heat and light.
The energy released during this process is what powers internal combustion engines, converting the chemical energy stored in gasoline into mechanical energy that moves vehicles. This transformation is essential for the functionality of most cars and trucks, making gasoline a vital energy source in the transportation sector.
