A temperature of 50.0 degrees Celsius is the same as a Kelvin temperature of approximately

-223 K

223 K

273 K

323 K

The answer is 323 K.

Explanation:

The Celsius temperature scale is equal to - 273.15.

One kelvin is equal to the change of thermodynamic temperature that results in a change of thermal energy kT by 1.380649 * 10^-23 J.

Convert degrees Celsius to kelvins with this simple formula:

kelvins = [degree C] + 273.15

The formula to convert Celsius to kelvins is degree C + 273.15.

50 degree celsius = 50 + 273.15

= 323.15 = 323 K.
