0 K  =  -273 °C.

Add  49  to each side:     49 K  =  -224 °C.

Answer : The temperature, in degrees Celsius, of a substance with a temperature of 49 K is, \(-224^oC\)

Explanation :

Conversion of temperature from Kelvin to degree Celsius :

\(^oC=K-273\)

The given temperature is, 49 K

Now put given temperature value in above conversion, we get the temperature, in degrees Celsius.

\(^oC=K-273=49-273=-224^oC\)

Therefore, the temperature, in degrees Celsius, of a substance with a temperature of 49 K is, \(-224^oC\)
