A computer model represents infrared radiation leaving the Earth's surface. The model contains 200 carbon dioxide molecules for every methane molecule. All the methane molecules together absorb the same amount of infrared radiation as all the carbon dioxide molecules together.
What can be concluded about absorption in this model?
An average methane molecule absorbs less infrared radiation than an average carbon dioxide molecule
An average methane molecule absorbs the same infrared radiation as an average carbon dioxide molecule
An average methane molecule absorbs more infrared radiation than an average carbon dioxide molecule
Absorption by an average molecule cannot be compared when the gases absorb equal totals
