Question

which temperature is equal to 20 k?

Explanation:

Step1: Recall the conversion formula

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

Step2: Substitute the given Kelvin - value

Given $T_{K} = 20$ K, then $T_{C}=20 - 273.15=-253.15\approx - 253^{\circ}C$.

Answer:

-253°C
