Final answer:
The statement is false because the numerical value of a temperature in Celsius and Kelvin differ only by a constant offset of 273.15, making the size of one degree the same on both scales.
Step-by-step explanation:
The statement that the numerical value of any temperature expressed in Celsius is always different from the numerical value of the same temperature in Kelvin is false. Although the Celsius and Kelvin scales have different starting points, the size of one degree increment is the same on both scales. The Kelvin scale is an absolute temperature scale with its zero at absolute zero, and the Celsius scale has its zero at the freezing point of water. The conversion between Celsius (Tc) and Kelvin (Tk) temperatures is given by the formula Tk = Tc + 273.15. Therefore, while their numerical values at a given point will differ due to the 273.15 offset, the magnitude of a temperature change is identical in both Kelvin and Celsius.
