Question

Select the gases which can absorb IR- radiation:

Oxygen, carbon dioxide, methane, nitrogen , chlorofluorocarbons

Answer 1

Carbon dioxide, methane, chlorofluorocarbons.

because Water vapor, carbon dioxide, methane, and other trace gases in Earth's atmosphere absorb the longer wavelengths of outgoing infrared radiation from Earth's surface. These gases then emit the infrared radiation in all directions, both outward toward space and downward toward Earth.
