When you do that, you'll find that the answer to your question is 277 K.

Answer 2

The answer is 277.15 K (approx.). The Kelvin scale starts at absolute zero and is used in scientific laboratories. Celsius is for general use and set 0 and 100 as melting and boiling point of water respectively. To convert from C to K, add 273.15 to C.
