28. Which of these statements about greenhouse gases and the greenhouse effect is not correct? I. Greenhouse gases prevent infrared radiation from escaping through the atmosphere. II. To absorb infrared radiation, a molecule must have a vibration that produces a change in the dipole moment of the molecule. III. Argon is the third most abundant species in the atmosphere (after nitrogen and oxygen), and therefore is a significant greenhouse gas. IV. The average amount of carbon dioxide in the atmosphere...
