Please i am so stuck on this question.
Thanks Konka.

nuclear - radioactive metals are used in reactors to heat water, making steam, turning a turbine, generating electricity
chemical - thermite, sodium metal (meaning the metallic, elemental form rather than an ionic form - highly reactive and can be used to create welds in metal working or explosives respectively
antimatter - in theory, if you have some anti matter, ANY normal matter, including metal, could be used as the one half of the fuel in the two part reaction. it is also THE perfectly efficient reaction - complete conversion of matter to energy. dense metals would be good for this purpose as the higher the density, the more fuel you can fit in a given space - mass, any mass would be the same, again, in theory.
Is this site becoming the location to go to when you are taking a test? If so, why do teachers let students have internet access during a test?
The desperation, time sensitivity, and simplicity of some of the questions is astounding and its the only explanation that makes sense to me to be honest.
Got to love that if I'm right, these kids are going to be running the world someday... without having a clue how.
Michael - that is a way of transferring energy, but the metal is not a fuel in that case - it isn't being used up in any way, simply heated and cooled.
DT - In a battery, the redox reaction is chemical in nature, but the metals are not fuel; they are a catalyst meaning they are a facilitator but are not used up in the reaction.
Sandy - magnets don't make energy.
Moving magnets can be used to induce electric current - that is the motion of the magnet can be converted into electricity (generator), or electricity can be used to move a magnet (electric motor).
In the case of generating electricity, the magnets physical motion had to come from somewhere else first.

The simple answer is plutonium and uranium both can be consumed as fuel in nuclear reactors. In most other other cases, the metal isn't a true fuel.

Conventional fuels are compounds of hydrogen & carbon elements. Metals are elements or alloys of elements. The only way you could get energy out of metal would be through nuclear reaction of suitable metals, eg Uranium metal or it's isotopes.

Use the metals to create batteries. Investigate Redox reactions.

You can heat up a large piece of metal , get it really hot then move it to a location where you want it warmer and either just let it sit there or blow air accross it slowly .

Chuck - no carefully place - a lump of sodium onto the surface of some water, and use the heat from the flame which ensues.

Magnets make electricity, the iron ore is metal, so one can make a useable Fuel source from metal.

Put magnesium ribbon in a flame, that will keep you warm for a few seconds.

lots of powdered metals make effective combustions
