Yes. Any thing that combusts (burns) can be used as a fuel (some examples are: wood, coal, oil, gas, hydrogen, food, etc)
No, wood is a combustible material because it can burn when exposed to heat and oxygen. It is commonly used as a fuel source for fires.
its doesnot seems practical but we can hypothetically say that, by dissociating H2O molecule to H2 and O2 by hydrolysis can act as fuel because h2 is combustable and O2 supports combution.
yes
Yes.
Some kind of combustable fuel,, ie... Gasoline.Propane.Kerosene. energy cannot be created but only "transfered" so the same goes for a generator, it needs something to fuel itslef to produce electricity..
Only in extreme heat.
Water can be a product of combustion.
A combustable engine
Phosphorus is combustible which means that it is flammable.
Sometimes there are gases that are combustable.
if its combustable it releases energy when it burns
Any vehicle that uses a combustable engine. Jet airplanes, and most cars and tucks are good examples. Train locomotives, and nuclear air craft carriers do not burn fuel to move. They burn fuel and convert and store the energy. But they do not use the energy produced from burning fuel to directly power their movement.
