Oxygen condenses into a liquid at approximately 90.2 K. To what temperature does this correspond on both the Celsius and Fahrenheit temperature scales?

Answer 1

To convert from Kelvin (K) to Celsius (°C) and Fahrenheit (°F), we can use the following formulas:

1. Celsius (°C): \[ °C = K - 273.15 \]

2. Fahrenheit (°F): \[ °F = °C \times \frac{9}{5} + 32 \]

Starting with the conversion from Kelvin to Celsius:

\[ °C = 90.2 , K - 273.15 = -182.95 , °C \]

Next, we convert Celsius to Fahrenheit:

\[ °F = (-182.95) \times \frac{9}{5} + 32 \]

Calculating the multiplication:

\[ °F = -327.31 + 32 = -295.31 , °F \]

Therefore, the temperature corresponding to 90.2 K is approximately:

• Celsius: -182.95 °C
• Fahrenheit: -295.31 °F
