What gas do all fuels need in order to burn?

Hi there!

All gasses and engines need fuel to burn because the heat or chemical reaction from the burning fuels are converted into different types of energy that fuel (or help fuel) the engine or gas.

Hope this helps!

Good Evening,

Burning is also called more formally as a combustion reaction. Combustion reactions are exothermic redox reactions. These types of reactions are usually required to have two components. A reductant (Fuel if you will, like wood or gasoline) and an oxidant like (Unsurprisingly) Oxygen gas.

Hope This helped B) 

Aconductor easily transfer heat
