How does the atomic hydrogen or oxy-hydrogen torch funtion for cutting and welding purposes? Explain.

Text Solution

Verified by Experts

Atomic hydrogen is produced when molecular hydrogen electrodes (3773-4273K).
`H_(2)underset(3773-4273K) overset("Electric arc")to 2H, DeltaH=435.9 KJ "mol"^(-1)`
The lifetime of atomic hydrogen is 0.3 sec . And hence it immediately gets converted into the molecular form liberating a large amount of energy which is used for cutting and welding purposes in form of atomic hydrogen torch as shown in Fig. 9.13
