Ejercisio pendiente

Dear all, from the questions related to the fluctuations of the coefficients of the work differential, we still don't have any good solution for the last question. In the case of the atoms in a onedimensional harmonic trap, everything can be calculated without problems.

Work for an ideal gas in a 3D container (corrected)

Imagen
Using the differential al work calculated on exercise 6.2: 1. How can we use the result to obtain DW for an ideal gas in a 3D container? What is the interpretation of the parameter "a" in that case. Solution.  The differential of work calculated on exercise 6.2 is Here, d represents the dimension of the box. So The parameter a is the lenght, according to equation (67). Because we are working on  3 dimensions, a³=V . This might come from the definition of entropy*.      2. What do we get for DW for d=3 and n --> infinity? And how is this result related to the expected form DW = N k_B T dV/V?    Solution.  On the last expression we get DW for three dimensional case. Now, applying the limit on infinity, we expect that the differential of work would become on well potential one. So,
