Please don´t answer by partition equation! Consider the semiclassical model of N particles with two energy levels (0 and e > 0).Suppose that the volume of the gas may be introduced by the assumption that the energy ofthe excited level depends onV =ae = e(v)vr'E =where a and y are positive constants. Use the fact that the number of microscopic states ofthe system is given by:N!N!N(E, N) :N4! (N – N,)! (E/e)! (N – E /e)!Obtain an equation of state for the pressure, p = p(T,v), and an expression for the isothermalcompressibility (note that the constant y plays the role of the Grüneisen parameter of thesolid). Again, as e =:E(v), we can write s =s(u, v).From the equations of state, it is easy to write the isothermal compressibility.

Could someone explain to me in detail why bringing a crystal substance to absolute zero isn't possible? I know it's not because of quantum mechanics and uncertainty like some people say, because particals at their lowest zero-point will have a temperature of exactly 0 K, even though they're still experiencing motion. From what I've gathered, the energy or time required to pull it off is infinite, but I can't find any equations or clear explanations as to why or how that is. And I also don't know if there's any other reasons beyond that. If you could give me a thourough a breakdown for how absolute zero is impossible as you possibly could, I'd greatly appreciate it. Take as much extra time as you need. As long as it's detailed and correct I'm happy. Though ideally I would before it come in before the end of the day.
