Heat, fire, pressure - things i don't understand
Apologies if this is in the wrong location, i'm new (and using that as an excuse :) )
i am currently working on a fantasy novel and having some issues that my days old knowledge of thermodynamics, and what-not, is nowhere near capable of managing.
So, to dive straight in; if we were to assume that you had access to a large amount of energy (potential or otherwise) and chose to use said energy by transferring it to a point in the air in front of you to generate a high temperature (thousands of degress) would a flame appear? Or, is a flame only generated when a secondary material is introduced, such as wood, carbon etc?
if you were to heat to a small part of the air in front of you quickly and highly enough would you create a shockwave which would 'push' things?
any help, knowledge or nudges in the right direction would be greatly appreciated.

You wouldn't create a flame - a flame needs fuel+oxygen+heat.
You could create a plasma if you heated it enough - like a spherical glowing spark
Enough heating can create a force, lightning creates a supersonic shock by heating air - that's the thunder you hear.

If some of the nitrogen were oxidized would there be a visible flame?
