Degenerate matter When gas become super-compressed, particles bump right up against each other to produce a kind of gas, called a degenerate gas , that behaves more like a solid. Normal gas exerts higher pressure when it is heated and expands, but the pressure in a degenerate gas does not depend on the temperature. The laws of quantum mechanics must be used for gases of ultra-high densities. The first rule is that only certain energies are permitted in a closely confined space. The particles are arranged in energy levels like rungs of an energy ladder. In ordinary gas, most of the energy levels are unfilled and the particles are free to move about. But in a degenerate gas, all of the lower energy levels are filled. The second rule is that only two particles can share the same energy level in a given volume at one time. For white dwarfs the degenerate particles are the electrons. For neutron stars the degenerate particles are neutrons. The third rule is that how close particles can be spaced depends
