Which is a gas at room temperature?

B) Nitrogen is a gas at room temperature because it has a low melting point and a low boiling point. In fact, you would have to bring down the temperature of nitrogen to about -197 degrees Celsius in order for its gaseous form to condense into a liquid.

Fun fact: About 78% of the air we breathe consists of nitrogen.
