well, then you can certainly give us a description of the physical
mechanism whereby the chambers containing methane (lighter than air)
and carbon dioxide (heavier than air) both warmed faster than air, due
to their "density and thermal properties".

You will no doubt have noticed Bilbo has been unable to do this, for
the entire time the 'school experiment' debate has has been going.

Because if you properly do the experiment, methane warms slower since
in has a lower heat capacity than CO2 but a higher heat capacity than
O2 and N2. Heat capacity is not the property of greenhouse gases. It
is criminal fraud to produce false exhibits it which it is portrayed
as the property of greenhouse gases.

Some of the methane must be oxidizing. This oxidation does not become
a continuing reaction within the gas, but occurs with individual
molecules with the help of the high energy photons of the visible
light and high energy infrareds.
Methane only lasts in the atmosphere for 12 years before it naturally
oxidizes into CO2 and water vapor. Therefore if you take the molar
value of enthalpy of oxidation of methane, divide by Avagadro's
number, you have the energy actually released when one molecule
oxidizes.
