What is the boiling point of oxygen?

• A. -200C
• B. -183C
• C. -150C
• D. -180C

Answer: (B)

The boiling point of oxygen is indeed crucial information in various fields, including medicine and engineering. Oxygen, as a gas at normal temperatures and pressures, transitions to a liquid state at a temperature of -183 degrees Celsius. This transition point is important in understanding how oxygen is stored and delivered in liquid form for medical and industrial applications.

The choice of -183 degrees Celsius aligns with established scientific data, marking the temperature at which oxygen's gaseous form condenses into its liquid state. This knowledge is essential for the safe handling and administration of oxygen in clinical settings, particularly in anesthesia and critical care, where the properties of gases like oxygen play a fundamental role in patient management.

The other numerical values presented represent temperatures that do not correspond to the known boiling point of oxygen, thereby confirming -183 degrees Celsius as the correct and relevant answer.
