What is the temperature in Celsius at 4 K, which is the normal boiling point of liquid helium?
A) -269°C
B) 269°C
C) 277°C
D) 68.3°C
E) -277°C

Question

Quizplus · Accepted Answer

At 4 K, the temperature in Celsius would be -269°C, as 0 K (absolute zero) is equal to -273.15°C. The normal boiling point of liquid helium is 4.22 K, which is approximately -268.93°C. Thus, at 4 K, the temperature is below the boiling point of helium, and therefore would be much colder, around -269°C. Therefore, the best choice is A.
