Definition - What does Combustible mean? Combustible is a property of a substance that will burn as a result of fire or a chemical reaction. This is an important characteristic when materials are being used in the workplace, for construction or are being stored.
Hydrogen is the only combustible element, other elements, need an interaction with something else other than its self to be combustible. Therefore Hydrogen is the only fuâ¦el. Fuel such as gasoline have bonds to Hydrogen that bulk it up, slow it down, and generally make Hydrogen dense.
