Atomic hydrogen is used to produce atomic hydrogen torch to attain the temperature of 4000 – 5000⁰C which is employed in welding aluminum alloys, high chromium and nickel steels. It is based on the fact that when a jet of hydrogen is passed through an electric arc set up between the tungsten rods atomic hydrogen is produced which at once recombine to give a flame having a temperature between 4000 – 5000⁰C. The heat is not producing by burning of hydrogen but from recombination of hydrogen atoms.

H + H → H₂ + 104 K.cal/mole

Moderator Note

Getting a little tired of this, but I will copy paste the mod note into all of the offending threads.

 

Does this thread have a point for discussion? If not, I will be closing it and asking you to stop posting these sorts of threads in the future. They are a waste of space and do not belong on a discussion forum.
