OK, let's try this again. When you take a course in any of the hard
sciences, you either work the homework problems, or you ended up
ignorant.
I will bet you never worked any of the homework problems at the end of
each chapter. .

That is cute. So let's see your homework. You are only indoctrinated with
a bunch of information you can repeat. Your education gives you no ability
to review and rationally analyse problems.
So do you want to talk about my education? Just a diversion for someone
who does not understand his psuedo scientific indoctrination and cannot
discuss this very simple topic.
What do you want to discuss next, Aristotle. Philosophy, exsitentialism,
moral authority of scientists, the benefits of buying a $100,000 dollar
piece of paper called a diploma, which you can hang on a wall but gives
you no capability to discuss this simple problem which shows your
indoctrination to be incompletely invalid and useless??
The laboratory facts are this:
A gas injected into a container will bring the substance of the container
to it's temperature.
If a metal container is injected with N2 gas, the container will come to
the temperature of the gas. At this time, the outside surface of the
container has a quantity of energy leaving it's surface according to
Boltzman Stefan, 5.67E-5 ergs, cm-2, sec-1, degK-4.
THESE ARE FACTS. THE QUANTITY LEAVING THE SURFACE OF A HEATED BODY IS
DEFINED BY BOLTZMAN STEFAN.
This energy is a quantity and is always in compliance with the law of the
conservation of energy.
IT IS IMPOSSIBLE THAT THIS ENERGY IS TRANSFERED BY MERE COLLISIONS OR
CONDUCTION OF THE MOLECULES. ALTHOUGH THIS IS ABSOLUTELY ESSENTIAL TO THE
THEORY OF GRENHOUSE GASES.
If the temperature of the gas entering the container is increased but it
is allowed to expand, the pressure remains the same.
It's easier for me to think about it as the gas being held at constant
pressure, such as with a weighted frictionless piston at the top of a
cylinder. Then when the gas is heated, the piston rises, doing mechanical
work without changing pressure.
The collective energy
of the collisions of the molecules is therfore the same. However, energy
leaving the surface of the outside of the container increases as a
fourth power to temperature. From 300K to 1000K, this is a 12,226%
increase in energy.
KD, when the gas and container system radiates energy away, it cools,
unless an equal amount of energy is supplied to the system from outside
the system boundary.
