If the Celsius temperature is -50 C, what is the corresponding temperature in Kelvin?

If the Celsius temperature is -50 C, what is the corresponding temperature in Kelvin?

• A. 223 K
• B. 50 K
• C. 323 K
• D. 223 C

Answer: (A)

Kelvin = Celsius + 273.15. That offset shifts the Celsius scale to align with absolute zero in Kelvin. So, -50 °C + 273.15 = 223.15 K, which rounds to 223 K. The other options mix up the scales or the offset: 50 K would be around -223 °C, 323 K corresponds to 50 °C, and 223 °C is just a Celsius value misconverted to Kelvin.
