Joule [J] is unit of energy, not force [N]

 

J = kg*m^2/s^2

N = kg*m/s^2

 

1 ton is 1000 kg

 

1 ton could have energy E=m*c^2=1000 kg * (299,792,458 m/s)^2=1000 * 89875517873681764 = 8.988*10^19 J

 

but you would need 1 ton of antimatter to release that all energy..

Ton of hydrogen and antihydrogen will release the same amount of energy as ton of f.e. carbon and anticarbon.

So material doesn't really matter when we're are interested just about matter-energy conversion rate.

searching 'joules in a ton'

 

#1 4,184,000,000 joules in 1 ton of explosive. Convert ton to joule - Conversion of Measurement Units

 

#2 Coal produces heat energies of 28 million to 38 million joules per 2.2 pounds Energy in a Ton of Coal @ The Physics Factbook [so mean =33 million joules and 2,000lb/ton divided by 2.2lb=909 33000000*909=29,997,000,000 joules/ton of coal

 

#3 1 ton of oil equivalent = 41,868,000,000 joules Tons of oil equivalent to joules (TOE to J)

Define 'obliterate'.

 

Setting fire to the wood is an exothermic reaction According to the interweb there is "Between 25.8 and 36.6 million btu per cord, depending on type and condition". A ton of oak is about 1/2 cord. Mean BTU's in 1/2 cord=15.6 million Converting BTU to Jules is 16458871301 Jules/ton.

How high from what altitude on what planet?

Force has unit Newtons.

Energy has unit Joule.

 

You can't say "joules of force".

 

In physics we don't use word "obliterate". Do you rather meant annihilation?

 

how many joules does it take to lift 1 ton?

Potential energy = m*g*h

m - mass in kg

g - Earth's acceleration 9.81 m/s^2

h - relative height

To rise 1000 kg for 1 meter, you would need 1000 kg * 9.81 m/s^2 * 1 m = 9810 J.

If you just leave the diamonds for long enough they will obliterate themselves.

Diamonds are not stable and slowly convert to graphite.

The process is far too slow to be observable.

 

The real problem here is that you are mixing up units.

Your question is like asking "how many feet is hot enough to boil an egg?" or "how many seconds is wide enough to cross that atlantic?"

 

Force isn't measured in Joules.

 

Also, the force needed to damage something depends on lots of other factors- most importantly the area.

For example, I can stand on a plate of steel that is a square, one metre on each side and 12 cm thick (which will weigh about a ton) and my weight will not damage it.

 

But if I made all that steel into a really long thin wire, it wouldn't hold up it's own weight, never mind holding my weight too.
