Here's a fun experiment for you to try! Maybe start a thread with your results?
How can I see for myself that CO2 absorbs heat?
This experiment can be done at home or in the classroom. Fill one soda bottle with CO2 and fill a second bottle with ambient air. If you expose them both to a heat lamp, the CO2 bottle will warm up much more than the bottle with just ambient air. Check the bottle temperatures with a no-touch infrared thermometer. You’ll also want to make sure that you use the same style of bottle for each, and that both bottles receive the same amount of light from the lamp.
It would be better to use a container made of salt. Salt is completely heat transparent. But you would still need to account for the barometric pressure (inside and outside).
