What is the boiling point of nitrous oxide at atmospheric pressure?

The boiling point of nitrous oxide (N2O) at atmospheric pressure is approximately -88.5°C (-127.3°F). This means that at standard atmosphere, nitrous oxide will transition from a liquid state to a gas at this temperature. It's important to note that the boiling point is a critical property for understanding how nitrous oxide behaves during various phases of its use, particularly in applications such as rocket propulsion and as an oxidizer in hybrid rocket engines.

The significance of boiling point also extends to safety and handling, as it indicates the conditions under which the gas can safely be stored and used. In contrast, the other temperature options do not reflect the actual boiling point of nitrous oxide, highlighting the vital role of accurate measurements in the study and application of rocket propellants and other gases. Understanding these properties can significantly influence operational procedures and design choices in rocketry.
