Using Boltzmann’s equation, calculate the entropy of a system consisting of one mole of gas in which each molecule of gas has 10 possible microstates. How does this value compare with the standard molar entropy of helium gas (see lecture slides for examples of standard values!). (Boltzmann’s constant k = 1.38 x 10-23 J/K)

The Sackur-Tetrode Equation gives the entropy of a sample of n moles of monatomic ideal gas as a function of its internal energy U and volume V S(U, V) = 5/2 n R + n R In (V/n N_A(4piM U/3nN^2_Ah^2)^3/2) In the equation, R is the gas constant, M is the molar mass, N_4 is Avogadro's number, and h is Plank's constant. The equation can be derived using S = k ln W and directly computing W, the number of...

Positional Entropy: Starting from our equation S = kB ln W, we can work out the entropy associated with the simple position of molecules within a space. Let us assume we have a collection of N molecules, each one of volume Vm located within a volume V such that N*Vm << V. First, let us think about how many possible ways we can place one molecule within the volume V. There will be V/Vm possible locations. How many ways are...
