Using the relation K = C + 273, what is the Kelvin temperature corresponding to -273°C?

Explanation:
Kelvin temperature is found by offsetting Celsius by 273, reflecting that Kelvin starts at absolute zero while Celsius starts at the freezing point of water. So the relation is K = C + 273. If you take -273°C and add 273, you get K = -273 + 273 = 0, which is 0 kelvin. This is absolute zero, the lowest limit for temperature in the Kelvin scale. It’s the reason negative values in Kelvin aren’t used. For reference, 0°C is 273 K, not -273 K, and mentioning -0 K is just another way of writing 0 K.
