Current Question (ID: 17858)

Question:

$\text{... is not a greenhouse gas :-}$ $1.\ \text{Hydrogen}$ $2.\ \text{Carbon dioxide}$ $3.\ \text{Methane}$ $4.\ \text{Nitrous oxide or } \text{N}_2\text{O}$

Options:

1. $\text{Hydrogen}$
2. $\text{Carbon dioxide}$
3. $\text{Methane}$
4. $\text{Nitrous oxide or } \text{N}_2\text{O}$

Solution:

$\text{(1) HINT: } \text{H}_2 \text{ is not a greenhouse gas.}$ $\text{Explanation:}$ $\text{A greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect.}$ $\text{The primary greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone.}$ $\text{Hydrogen is not a greenhouse gas. Greenhouse gases must contain different atoms that are able to vibrate in a specific pattern to absorb heat energy.}$
