Gasoline is a form of chemical energy. When it is burned, the chemical energy stored in the bonds between the hydrogen and carbon atoms is released as heat and light. This energy can be used to power engines, such as those in cars, trucks, and airplanes.
The energy content of gasoline is measured in British thermal units (BTUs). One gallon of gasoline contains about 115,000 BTUs of energy. This means that burning one gallon of gasoline can produce enough energy to heat a 1,000-square-foot house for about 24 hours.
