Is O2 a greenhouse gas

Answer 1

No, it isn't. Water vapour, though, is a greenhouse gas.

To be greenhouse gas the molecule must have a strong absorbence in the IR frequencies of light. Neither oxygen nor nitrogen (the major gases in the atmosphere) have this characteristic.

To be a greenhouse gas the molecule must have at least three atoms. Water vapor is the most prevalent greenhouse gas in every measurable way. Carbon dioxide comes in a distant second with 0.04% of the atmosphere and about 5% of all warming. The rest of the gases that are involved are even more removed from the major gases in terms of warming and concentrations.

Answer 2

Oxygen has only two atoms (O2). A greenhouse gas must have three atoms or more so they can capture the infrared radiation and stop it leaving the atmosphere. So gases like oxygen and hydrogen (H), for example are not greenhouse gases. Carbon dioxide (CO2) and Methane (CH4) are greenhouse gas.

Answer 3

Generally, gases need three or more atoms to work as a greenhouse gas, that is, to warm up when struck by infrared radiation (from the surface of the earth). So Oxygen (O2) is not a greenhouse gas.

Answer 4

Absolutely! The depletion of ozone in the Antarctic is why science experts claim that the ice is not melting in the area.

Ozone, any virtually all gases with three or more atoms is a greenhouse gas.

Answer 5

no. Carbon dioxide is, as is water vapor. Greenhouse gases tend to be gases that have at least three atoms.

Answer 6

Yes, ozone is a greenhouse gas. It acts like a pollutant at the surface level of the earth.

Answer 7

O2 is oxygen, so no. it isn't.
