Question 170

A student wishes to calibrate a liquid-in-glass thermometer with a Celsius (∘C^\circ\text{C}∘C) scale.

Which physical temperatures should be chosen as the lower fixed point and the upper fixed point?

A

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

B

Lower fixed point: freezing point of the thermometer liquid; Upper fixed point: boiling point of pure water

C

Lower fixed point: melting point of pure ice; Upper fixed point: boiling point of the thermometer liquid

D

Lower fixed point: freezing point of the thermometer liquid; Upper fixed point: boiling point of the thermometer liquid
