In the previous chapters we have established that the ether contains a gaseous component that is responsible for electric effects.
Since this is a gas, laws that govern gasses will apply.
We are familiar with the ideal gas law: Pressure x Volume = Boltzmann constant x Number of molecules x Temperature
We can intuitively see that for electricity Pressure relates to Voltage, Volume to Capacitance and Number of molecules to Charge. But upon closer inspection and considering the units, we will see that Pressure is better described by Voltage² (squared) and that Number of molecules can differ significantly from Charge as the particles that make up this medium are not electrically charged.
But the most important observation is the introduction of Temperature into the realm of electromagnetism.
We already are aware of some thermo-electric effects, but we may find a much more fundamental relationship here.
It is probably good to take one step back for a while and think about what Temperature means or could mean with respect to electricity.
The particles of this medium are always moving in a random fashion, the so-called Brownian motion. When considering a very large number of particles, the group as a whole will stay in place as an equal number are moving to the right as there are to the left, etc. The kinetic energy of these particles is what makes up the temperature. If there is a translatory motion of the group as a whole, then that motion does not contribute to the temperature.
If there was a way to align the motion of all constituting particles, the temperature would drop to zero and all energy would be kinetic energy of the whole. (temperature would change to flow-energy).
This is nothing new as it is already implied by the ideal gas law mentioned earlier. If we pressurize a gas and let it escape through a nozzle we are in fact aligning the motion of the constituting particles and thus changing temperature into translatory motion. The temperature therefore drops.
In an electrically charged medium, this effect would be amplified by the magnetic effects that the moving charges create, causing the charges to attract eachother.
