Question 63

An engineer calibrating a liquid-in-glass thermometer defines the standard lower and upper fixed points using pure water at standard atmospheric pressure. If she wishes to mark these same calibration points on the thermodynamic (Kelvin) scale, which row in the table below correctly identifies their Kelvin temperatures?

Lower fixed point (K)Upper fixed point (K)A0100B0273C273373D273100 \begin{array}{|c|c|c|} \hline & \text{Lower fixed point (K)} & \text{Upper fixed point (K)} \\ \hline \text{A} & 0 & 100 \\ \hline \text{B} & 0 & 273 \\ \hline \text{C} & 273 & 373 \\ \hline \text{D} & 273 & 100 \\ \hline \end{array} ABCD​Lower fixed point (K)00273273​Upper fixed point (K)100273373100​​
