To transform a temperature from °C to K, we just have to apply the formula:
[tex]T(k)=T(\~C)+273.15[/tex]Where T(k) is the temperature in kelvin and T(C) the temperature in Celcius, let's replace 100 °C and calculate the equivalent temperature in kelvin:
[tex]T(k)=100+273.15=373.15k[/tex]Then, the answer is 373.15 k
