Temperature Conversion: Kelvin to Celsius

What is the temperature, in degrees Celsius, of a substance with a temperature of 49K?

A. -322°C

B. -224°C

C. 224°C

D. 322°C

Answer:

The correct temperature in degrees Celsius for a substance with a temperature of 49K is -224°C.

When converting temperature from Kelvin to Celsius, you need to subtract 273 from the temperature in Kelvin. In this case, the temperature given is 49K. By substituting this value into the formula, we get:

T(°C) = 49K - 273

T(°C) = -224°C

Therefore, the temperature of the substance in degrees Celsius is -224°C.
