Can you help me understand this experiment?

[Docfeelgood]

I find this a little confusing. If the tube of c02 was absorbing the heat/IR from the candle?
1. Why does the camera not show the tube getting warm? or showing the absorption of the IR?
2. How do they know the tube was getting warm if there was no way to measure the heat inside the tube?
3. Could the c02 be reflecting the heat rather than absorbing?

Can you help me understand?

The tube IS getting warmer, but really slowly. It is also cooling down by contact with the surrounding air. If you isolated the tube, it would take a while for it to heat up enough to start to irradiate on the IR wavelength. Non-isolated, even longer (if at all).

2. How do they know the tube was getting warm if there was no way to measure the heat inside the tube?

Law of conservation of energy.

3. Could the c02 be reflecting the heat rather than absorbing?

some might be reflected, but most gets absorbed.

Some is promptly scattered at a wavelngth similar to the input wavelength (spread out by the vrownian motion of the scattering molecule). Some is absorbed as heat and later reemitted at a large spread of frequencies. The atmosohere consists of a giant mound of tiny elements like the tube. Basic transport theory tells you the overall effect.

Bull****, you can't be certain that the law of conservation of energy was applied, if there was no way to measure it.

Mostly true. To get that reduction of the flames IR emmission, that tube have to be filled with CO2 wich isn't exactly the case for the atmosphere - though, I may be wrong if you really mean atmosohere .

You're a twit who is unfit to judge the truthfulness of what I said...
