To convert a temperature from Kelvin to Celsius, we use the formula:
[tex]\[ T(°C) = T(K) - 273.15 \][/tex]
Given:
[tex]\[ T(K) = 49 \][/tex]
We substitute the given Kelvin temperature into the conversion formula:
[tex]\[ T(°C) = 49 - 273.15 \][/tex]
Subtracting these values will give us the temperature in degrees Celsius:
[tex]\[ T(°C) = -224.15 \][/tex]
The closest match to this value from the given options is:
[tex]\[ -224^{\circ} C \][/tex]
So, the temperature of the substance in degrees Celsius is:
[tex]\[ -224^{\circ} C \][/tex]
