What would happen to this planet if say had 100kg of something say iron and it became 142,000,000,000,000,000,000,000,000,000,000 K hot?

Would it ignite the earths atmosphere?
 
Only if an aircraft landed on a treadmill while the co-pilot maintained a boxing stance with a loaf of hovis under his arm while delivery letter post and being watched by avec dino.

:D

Only people born before 1990 will understand this post.

a) it wouldn't be iron any more

b) it would probably weigh a lot more than 100Kg

As for the earths atmosphere, Fortunately the earths atmosphere is somewhat resistant to catching fire otherwise lightning bolts, Hydrogen bombs and even asteroids would have done for us all by now.

(There was some speculation with the Trinity test as to whether the Gadget would set the atmosphere on fire. I hope the speculation was tongue in Cheek, if there really was a concern. proceding with the test would have been an act of total insanity! :eek: )
 
As chance would have it, the earths atmosphere would set fire at 142,000,000,000,000,000,000,000,000,000,000K and 142,000,000,000,000,000,000,000,000,000,000K only.

Not 142,000,000,000,000,000,000,000,000,000,001K.
Not 141,999,999,999,999,999,999,999,999,999,000K.
Exactly 142,000,000,000,000,000,000,000,000,000,000K.

So to answer your question, yes.
 
Dunno black hole maybe?
Where do you get the energy to make something that "hot" ?
Deffo Tshirt and ice cream day.
 
That's way more than enough heat for every atom to be stripped of its electrons, and prised apart from every other atom. Probably hot enough to destroy the nuclei as well.
The entire planet would vaporise in seconds. It'd be far more than the 'atmosphere catching fire'.

That's trillions of times hotter than the core of the sun! It would not end well.
From early science lessons, iirc, a grain of sand at 15 million C would destroy everything for about a 10 mile radius...

Pretty sure my girlfriends shower is hotter than that.

On a serious note it's impossible by our physics we will never know apart from it would most certainly end in destruction.

i heard/read that there were serious questions as to whether or not the atom-splitting would stop at the bomb's material or if the chain reaction would continue into the atmosphere/every other atom on Earth. Dunno how true it is, be a bit disconcerting if the decision was "...dunno, let's see."
