Gasoline:

Gasoline is a liquid fuel made from carbon compounds called hydrocarbons. It is obtained by the fractional distillation of crude oil which purifies chemicals based on their different boiling points.

Answer and Explanation:

Burning gasoline is exothermic. This is because burning gasoline releases heat energy and exothermic reactions are by definition reactions which release energy into the environment. The energy released by burning gasoline can be used to power motor vehicles and other machines.
