Q:

What three things does a fire need to start?

A:

The three things that are required to start a fire are fuel, oxygen and heat, which form the fire triangle. All three are dependent on one another, which means that a fire cannot be started if even one of them is missing.

Oxygen in the air interacts with flammable vapors that are produced by fuel, whereby it creates a form of heat at a molecular level. After that, any source of ignition, such as a spark or a match, can cause it to combust. The more easily a material gives off flammable vapors when exposed to heat, the easier it is to start a fire.

  • Q:

    Why do things burn?

    A:

    Burning is a chemical reaction that involves the outer electrons of the substances. Usually, oxygen is one the elements, and something else that has excess electrons is the other. All chemical elements that aren't stable seek to become stable by the addition or subtraction of electrons. Oxygen needs two electrons to have a stable outer shell, and when it chemically reacts with a more electronegative substance, the result is fire.

    How does a fuel pump work?

    A:

    A fuel pump pulls gasoline from the tank, guiding it along a pipe to the carburetor. Some fuel pumps are electric, mounted near or in the fuel tank, while others operate mechanically in concert with the engine. Either way, the fuel pump is what gets the gasoline where it needs to go.
