At what temperature does helium liquify, which is equivalent to 4 degrees Kelvin?

• A. -273 degrees Fahrenheit
• B. -453 degrees Fahrenheit
• C. -397 degrees Fahrenheit
• D. -494 degrees Fahrenheit

Answer: (B)

Helium liquefies at a temperature of approximately 4 degrees Kelvin, which is equivalent to about -268.15 degrees Celsius. When converting this temperature to Fahrenheit, the calculation should yield a value around -452.1 degrees Fahrenheit. This highlights why the answer of -453 degrees Fahrenheit is the most accurate. The Kelvin scale starts at absolute zero, the theoretical point at which all molecular motion stops, which corresponds to -459.67 degrees Fahrenheit. Thus, temperatures close to absolute zero can yield very low Fahrenheit equivalents, placing -453 degrees Fahrenheit in the correct context for the liquefaction point of helium at 4 K. The other temperature options provided are not accurate conversions from 4 degrees Kelvin.
