Entropy of a 2d ideal gas
In general, 2D molecular gases are experimentally observed on weakly interacting surfaces such as metals, graphene etc. at a non-cryogenic temperature and a low surface coverage. As a direct observation of individual molecules is not possible due to fast diffusion of molecules on a surface, experiments are either … See more A two-dimensional gas is a collection of objects constrained to move in a planar or other two-dimensional space in a gaseous state. The objects can be: classical ideal gas elements such as rigid disks undergoing elastic collisions See more Research at Princeton University in the early 1960s posed the question of whether the Maxwell–Boltzmann statistics and other thermodynamic laws could be derived from Newtonian laws applied to multi-body systems rather than through the conventional … See more A multiplicity of theoretical physics research directions exist for study via a two-dimensional gas. Examples of these are • Complex quantum mechanics phenomena, whose solutions may be more appropriate in a two … See more • Riemann problems for a two-dimensional gas • Two-dimensional gas of disks See more While the principle of the cyclotron to create a two-dimensional array of electrons has existed since 1934, the tool was originally not really used to … See more In 1991 a theoretical proof was made that a Bose gas can exist in two dimensions. In the same work an experimental recommendation was made that could verify the hypothesis. See more • Bose gas • Fermi gas • Melting point • Optical lattice • Three-body problem See more WebAs the plots above show4, the ideal gas law is an extremely good description of gases at low densities. Gases deviate from this ideal behaviour as the densities increase and the interactions between atoms becomes important. We will see how this comes about from the viewpoint of microscopic forces in Section 2.5.

We start with the entropy S(T,V)−S(T0,V0) = 3nR 2 log T T0 +nRlog V V0 = 3nR 2 log U U0 +nRlog V V0 of the ideal gas, as derived in Sect. 4.4.1, where we have used the ideal gas relation U = 3nRT/2 to substitute T and T0 with U and U0 in the second step. 5.1.
