What is zero degrees Celsius in Kelvin? What is 100 degrees Celsius in Kelvin?

Explanation:
Key idea: to convert Celsius to Kelvin you add 273.15. So 0°C is 273.15 K and 100°C is 373.15 K. When rounding to whole kelvin, that’s about 273 K and 373 K. The option with 273 and 373 matches these rounded values, which is why it’s the best choice. The other options don’t align with the correct second value or the scale’s magnitude.
