All of your "mysteries" make perfect logical sense.
Cold gas is compressed and has more gas in a smaller space.
Hot gas expands and has less gas in the same space.
You are just a moron.

And since I haven't ran this image into the ground enough, here's the kinda shit I used to pull off routinely before the change.

this has nothing to do with moles.

It's ideal gas law.
pressure is proportional to temperature divided by volume.

Spoiler:

If we're going to talk about realism I think explosions in general are really shit in this game. The fact that it contains oxygen instantly means it's a low explosive involving conflagration, these are made from usually a combustible (plasma) and an oxidiser (oxygen). These are about as effective as firing a firework, because that is what they are.

An actual explosive compound usually has enough stored energy in of by itself that it doesn't need any oxidants. a simple physical stimuli will be enough to break said bonds and release the energy in a very short amount of time (that's all a explosion is at the end of the day, energy released in a very short time. If wood burnt entirely in under 0.1 seconds it too would be an explosion. There's also some things to do with gases being produced and therefor increase in volume but just take it as energy being released.) Some chemicals are so sensitive that even an alpha particle is enough to trigger them.

I would completely scrap plasma, yes, I know it's an integral part of the game or whatever but it's relied on a crutch far too often and honestly, the bomb making process is far too convoluted and usually involves using tricks more than anything to achieve the perfect bomb mix or whatever. Also it makes no sense if we're talking about it fundamentally, decreasing the energy of a molecule, doesn't matter how oxidising it is, does more harm than good in terms of a low explosive. I think that cooling down oxygen to that low will actually slow the rate of reaction so low that it may turn into a non spontaneous reaction, ΔS > 0 etc etc.

Just make bomb making involve fertiliser or whatever, with cooperation from the botanists or cargo in order to get illegal super strong fertilisers to make illegal fertiliser bombs and stash them into a security officers segway to bomb the heathens back to their false idol or whatever. It'll be far more accurate that this garbage we have.

A deflagration is characterized by a subsonic flame propagation velocity, typically far below 100 m/s, and relatively modest overpressures, say below 0.5 bar. The main mechanism of combustion propagation is of a flame front that moves forward through the gas mixture - in technical terms the reaction zone (chemical combustion) progresses through the medium by processes of diffusion of heat and mass. In its most benign form, a deflagration may simply be a flash fire. In contrast, a detonation is characterized by supersonic flame propagation velocities, perhaps up to 2000 m/s, and substantial overpressures, up to 20 bars. The main mechanism of combustion propagation is of a powerful pressure wave that compresses the unburnt gas ahead of the wave to a temperature above the autoignition temperature. In technical terms, the reaction zone (chemical combustion) is a self-driven shock wave where the reaction zone and the shock are coincident, and the chemical reaction is initiated by the compressive heating caused by the shock wave.

Under certain conditions, mainly in terms of geometrical conditions such as partial confinement and many obstacles in the flame path that cause turbulent flame eddy currents, a subsonic flame may accelerate to supersonic speed, transitioning from deflagration to detonation. The exact mechanism is not fully understood, and while existing theories are able to explain and model both deflagrations and detonations, there is no theory at present which can predict the transition phenomenon.
