Which one of the following is the correct relation between the Kelvin temperature (T) and the Celsius temperature (t_c)?
These are two independent temperature scales
T = t_c
T = t_c - 273·15
T = t_c + 273·15

– The Celsius scale is based on the phase change points of water at standard pressure (0°C for freezing, 100°C for boiling).
– The temperature 0°C corresponds to 273.15 K.
– The formula T = t_c + 273.15 correctly shifts the zero point of the Celsius scale to match the absolute zero of the Kelvin scale while maintaining the same interval size.
