The lowest temperature obtained under laboratory conditions is -273.13 degrees Celsius, which is 4.21 degrees Celsius

The lowest temperature obtained under laboratory conditions is -273.13 degrees Celsius, which is 4.21 degrees Celsius below the boiling point of helium, which is equal to the boiling point of helium.

From the condition of the problem, the lowest temperature obtained in laboratory conditions is – 273.13оС. Knowing that this temperature is 4.21 ° C lower than the boiling point of helium, we can find the boiling point of helium:

– 273.13 ° C + 4.21 ° C = – 268.92 ° C.

Answer: the boiling point of helium is 268.92 ° C.
