Can you help me understand this experiment?

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?
|
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. |
