Statistical Mechanics: Particles on a Sphere
$K$ identical particles of mass $m_0$ are bound to move on a sphere of radius R. The system is at equilibrium at temperature $T_0$.
1 - What's the internal energy ($E$)?
2 - What's the specific heat ...

Partition function of a 3D vibrating string
Is the partition function of a 3D vibrating string a sum of discrete energies, an integral of an energy continuum, or both?
$$
Z_{\text{disc}} = \sum_{k=1}^{\infty}g_ke^{-\beta E_k}
$$
or

Partition function microcanonical ensemble
I was wondering if there is a way to understand the partition function for a microcanonical ensemble $$\mathcal Z(E)=\sum_{\text{microstate $i$ with energy $E$}} w_i$$
as a limit of the continuous ...

Calculation of the partition function for a classical 2D gas lying on the surface of a sphere of constant radius $R$
I'm kind of confused with this system. My first question is. Is the Hamiltonian of one particle of this gas the following?
$$H(x,y,z,p_{x},p_{y},p_z)=\frac{1}{2m}\left(p_{x}^{2}+p_{y}^{2}+p_{z}^{2}\...
