Study Notes
Greenhouse Gases Characteristics
- A key characteristic of greenhouse gases is their ability to absorb and re-emit infrared radiation, trapping heat in the atmosphere.
- Polarity is essential for a molecule to be a greenhouse gas, as it allows them to take on energy from radiation.
- Molecules with a dipole moment, such as H2O and CO2, are more likely to take on energy from radiation due to their polar nature.
- Argon is not considered a greenhouse gas because it is a non-polar molecule, meaning it lacks a dipole moment and cannot absorb and re-emit infrared radiation.
- Infrared radiation gives energy to H2O and CO2 molecules, which they re-radiate in random directions, trapping heat in the atmosphere.
- A key characteristic of a gas to be considered a greenhouse gas is its ability to absorb and re-emit infrared radiation, which is dependent on the molecule's polarity.
Greenhouse Effect Process
- The main process by which greenhouse gases keep the Earth warmer is the trapping of heat in the atmosphere through the absorption and re-emission of infrared radiation.
