Question: 1 / 400

At what temperature does nitrogen change from a liquid to a vapor?

-100°F

-250°F

-320°F

The transition of nitrogen from a liquid to a vapor occurs at its boiling point, which is approximately -196°C (-320°F). This is the temperature at which nitrogen changes phases from a liquid to a gaseous state under standard atmospheres.

Understanding this concept is essential in fields such as cryogenics and industrial applications where nitrogen is utilized in its liquid form for various purposes, including cooling and food preservation. This phase change is a fundamental property of nitrogen and reflects the intermolecular forces present in the liquid state, which become weak enough at this temperature to allow molecules to escape into the vapor phase.

The other temperature choices do not correspond to the boiling point of nitrogen, thus highlighting the significance of understanding the properties of elements and their behavior under different thermal conditions.
