Re: [TCML] Arc Temperature

hi,
this is just something to work with.  i dont have any books with me but get a thermo book and a sophmore physics book on electricity and then cobble this mess together:
when an electron falls thru an electric field of a certain voltage it reaches a certain velocity.  with ur arc pretend it fell thru 15 kv per centimeter.  now u can work out a velocity as it is a standard 2nd year physics problem. so now u can find a velocity. (dont let it exceed the velocity of a cosmic ray)
now in thermo there is a famous equation that relates speed with temperature: sorta like Vx + Vy + Vz =  (3/2) k T  where the V's are the speed of the particle in 3 dimensions.  but make it easy and say all the speed is on one axis, say Vx.  so now u got Vx = (3/2) k T.
Vx is the velocity u figured out from falling thru 15 kv.  k is Boltzmanns constant u have to look it up and not only get its numerical value but get its strange units.  T is the temperature u r looking for.  from the units of Boltzmann's constant u will know what units T is in, and u will know what units Vx is in (say meters per second).
so now as the smoke clears, u see that u can solve for the temperature (say degrees centigrade) of an electron that has fallen thru 15 kv.  and subtract a little off for collisions in the plasma..
anyway that's the idea.  its good to poke around a bit in Boltzmanns stuff cus the difference between him and einstein is that he really was smart.
by now,
