To calculate the temperature at which ruthenium becomes superconducting in degrees Celsius, you need to convert the given temperature from Kelvin to Celsius. The formula to convert Kelvin to Celsius is:
[tex]\[ \text{Temperature in Celsius} = \text{Temperature in Kelvin} - 273.15 \][/tex]
Given that the temperature at which ruthenium becomes superconducting is 0.655 K, we can use the formula to find the temperature in Celsius.
1. Convert the temperature from Kelvin to Celsius:
[tex]\[ 0.655 \, \text{K} - 273.15 = -272.495 \, \text{°C} \][/tex]
2. Round the result to three decimal places:
The temperature in Celsius, when rounded to three decimal places, is:
[tex]\[ -272.495 \, \text{°C} \][/tex]
Therefore, the temperature at which ruthenium becomes superconducting is [tex]\(-272.495 \, \text{°C}\)[/tex].
