What is the Celsius equivalent of a temperature of 10°C?

To convert Celsius to Kelvin, you add 273.15 to the Celsius temperature. Therefore, for a temperature of 10°C, the conversion to Kelvin would be calculated as follows:

10°C + 273.15 = 283.15 K

When rounding, this gives you approximately 283 K, which matches the chosen answer. This conversion is based on the fact that Kelvin is an absolute temperature scale starting at absolute zero, where 0 K is equivalent to -273.15°C. This relationship is fundamental in thermodynamics and other areas of physics.

The other options do not represent the correct conversion from Celsius to Kelvin as they do not take into account the necessary addition of 273.15 to the Celsius value.
