Question

Liquid helium boils at –268.93 °C. What is the boiling point of helium on the Kelvin temperature scale?

Answer 1

–268.93 °C on the Kelvin temperature scale is 4.07 °K.

To get Kelvin, you have to take Celsius and add 273.

Answer 2

Answer : The temperature in Kelvin is 4.22 K.

Explanation :

The conversion used for the temperature from degree Celsius to Kelvin is:

`K=273.15+^oC`

where,

`K` = temperature in Kelvin

`^oC` = temperature in centigrade

As we are given the temperature in degree Celsius is,
`-268.93^oC`

Now we have to determine the temperature in Kelvin.

`K=273.15+^oC`

`K=273.15+(-268.93^oC)`

`K=4.22`

Therefore, the temperature in Kelvin is 4.22 K.
