Question

the metal niobium becomes superconducting at temperatures below 3.722 k. calculate the temperature at which niobium becomes superconducting in degrees celsius. be sure your answer has the correct number of significant digits.

Explanation:

Step1: Recall temperature - conversion formula

The formula to convert Kelvin (K) to Celsius ($^{\circ}C$) is $T_{C}=T_{K}- 273.15$.

Step2: Substitute the given value

Given $T_{K}=3.722\ K$. Substitute it into the formula: $T_{C}=3.722 - 273.15$.

Step3: Calculate the result

$T_{C}=-269.428^{\circ}C$.

Answer:

$-269.428^{\circ}C$
