Question 298

An engineer is calibrating a liquid-in-glass thermometer to establish a Celsius (∘C^\circ\text{C}∘C) temperature scale.

Which pair of standard physical temperatures under standard atmospheric pressure should be used to define the lower and upper fixed points?

A

Lower fixed point: Temperature of freezing alcohol; Upper fixed point: Temperature of boiling alcohol

B

Lower fixed point: Temperature of pure melting ice; Upper fixed point: Temperature of steam above pure boiling water

C

Lower fixed point: Temperature of freezing mercury; Upper fixed point: Temperature of steam above pure boiling water

D

Lower fixed point: Temperature of pure melting ice; Upper fixed point: Temperature of boiling alcohol
