Heat
(Thermal Energy)
Heat is thermal energy that produces fuel gases (pyrolysis) and causes ignition.
Oxygen
(O2)
Oxygen is in the air. Just like we need to live, fire needs it to burn.
Fuel
(Chemical Energy)
Fuel is any substance that combusts after converting to a gas in the presence of heat, for instance, this couch.

Notice that when enough heat, oxygen, and fuel are present,
a chemical reaction occurs that produces fire.
The chemical reaction involving heat, oxygen, and fuel
is known as the fire tetrahedron.
During fire, chemical energy in fuel and oxygen is converted
into thermal energy, light energy and products like soot and smoke.
Fire needs certain components of matter and energy to ignite and keep burning.
