Guys, i am frustrated!
i don't know it well, and if someone who knows it really good could expalin me then i'll be more than thankfull! i devoted too many hours for this one:
question:
" find the value of the gruneisen for a crysal inert gas. use the lennard-jones potential."
i understand that the meaning of the gru' is to show dependence of V in temp' in anaharmonic models. i know that grun'=d(lnw)/d(lnV)
but i didn't understand how they got to it (anyone?). i know you need to use the hlmoltz free energy (F=U-TS), but somewhere in the middle of the prove of that in kittle, i got lost...
also kittle has no example for this one, so i don't get it. someone?
p.s
sorry for any bad english, my primary is hebrew... the question is translated from hebrew also...
