However, an example of a factor that affects the ability of your muscles to absorb oxygen would be the extent of the blood capillary distribution at your muscles (more blood capillaries means more surface area for oxygen absorption), and an example of a factor that affects the ability of your muscles to use oxygen would be the mitochondrial density of your muscles (mitochondria are organelles in your cells that are primarily responsible for the cellular respiration process that uses oxygen to create ATP energy).

The technical means of making needs to become incidental, so the density and the weight reside in the painting itself, where the energy is focused in a few square feet.

what exactly is it that determines the probability of an energy transition such as an electron emitting or absorbing a photon (besides densities and occupancies of states and incident photons, etc.)-- and how does refractive index affect this (it has to because the Planck function is proportional to n ^ 2 — has to be in order to satisfy 2nd law of thermo...)-- and does it make sense to use an k, E diagram when electrons are not actually propagating as plane waves — I mean, what is the wavevector when the waveform is not a plane wave; is k a function of space in atomic orbitals?

ie does a slightly lower density of air mean a slightly lower ground level temperature (temperature normally decreases with height at the lower air density), so that in reality adding CO2 and subtracting more O2 actually causes miniscule or trivial global COOLING, and the (unused) ability of the changed atmosphere to absorb radiation energy and transmit it to the rest of the air is overruled or limited by the ideal gas law?

It also has high power density, meaning that it produces more energy per gallon than many other liquid fuels.

As I understand the Ideal Gas Law, the temperature one measures depends on the density of the gas as less density means less collisions of individual molecules with the measuring apparatus, or IOW, less kinetic energy per volume unit of gas.

It also has relatively low energy density, meaning it can not realistically power airplanes, ships or even trucks, which would have to carry too much fuel to move their mass.

The density of CO2 concentration in the atm means that re-radiated IR energy from the ground, at the main CO2 absorption frequencies, can all be absorbed in the first 10 metres of air above ground.

I'll preface that by observing that nothing in your discussion of the first two flavors gives any reason to believe that you viewed temperature any differently from the Ideal Gas Law, which treats temperature as the ratio of pressure to the product of molecular density and Boltzmann's constant, i.e., as two - thirds the ratio of mean molecular translational kinetic energy to Boltzmann's constant.

As you can see, the authors there compute a mean kinetic energy for an altitude z by integrating, through all possible velocities, the product of (1) the kinetic energy associated with that velocity and (2) the velocity distribution density function evaluated for altitude z at that velocity.

So it's all gases at greatest density will be doing the same thing around the planet at the same time (*) and as these change with differences in density in the play between gravity and pressure and kinetic and potential from greatest near the surface to more rarified, less dense and absent any kinetic to write home about the higher one goes, then, energy conservation intact, the hotter will rise and cool because losing kinetic energy means losing temperature, thus cooling they which began with the closest in density and kinetic energy as a sort of band of brothers near the surface will rise and cool at the same time whereupon they'll all come down together colder but wiser that great heights don't make for more comfort and giving up their heat will sink displacing the hotter now in their place when they first went travelling.
