Degenerate matter and temperture

[Starwatcher16]

Why does the tempeture of degenerate matter corelate only weakly with density? I guess the more fundamental question is, why does it not act like a gas?

Note:I have only taken up to difyQ 1 and modern physics, so go easy on me :0

Degenerate matter is a state of matter that occurs at extremely high densities, such as in the cores of white dwarf stars or neutron stars. In this state, the matter is so tightly packed that the electrons are forced into higher energy levels, creating a high amount of pressure that supports the matter against gravitational collapse.

The temperature of degenerate matter is only weakly correlated with density because it is not governed by the same laws as a gas. In a gas, temperature is directly related to the average kinetic energy of the particles, and as density increases, the particles are more likely to collide and transfer energy, resulting in an increase in temperature. However, in degenerate matter, the particles are no longer free to move and collide due to the high pressure and density. Instead, the temperature is determined by the energy levels of the electrons, which are determined by the density and composition of the matter.

Additionally, degenerate matter does not behave like a gas because it is governed by quantum mechanics rather than classical mechanics. In a gas, particles can occupy any energy level and move freely, but in degenerate matter, the Pauli exclusion principle states that no two electrons can occupy the same quantum state. This means that as density increases, electrons are forced into higher and higher energy levels, resulting in an increase in pressure rather than temperature.

In conclusion, the temperature of degenerate matter is weakly correlated with density because it is not governed by the same laws as a gas and is instead determined by the quantum mechanical properties of the particles. This also explains why it does not behave like a gas and follows different rules for temperature and pressure.
