Quizplus · Accepted Answer

The boiling point of oxygen is given as 90.2 K, which is below the freezing point of water (273.15 K or 0°C). Therefore, the temperature is below 0°C on the Celsius scale. To convert Kelvin to Celsius, we subtract 273.15 from the given temperature. Thus:
90.2 K - 273.15 = -182.95 ≈ -182.8°C
Therefore, the correct answer is D.

The Boiling Point of Liquid Oxygen Is 90
