Question 300

To calibrate a liquid-in-glass thermometer on the Celsius scale, two standard fixed points are used. Which of the following describes these two fixed points under standard atmospheric pressure?

A

The temperature of melting pure ice (0∘C0^\circ\text{C}0∘C) and the temperature of steam above pure boiling water (100∘C100^\circ\text{C}100∘C)

B

The lowest and highest temperatures that the thermometer scale can measure (−10∘C-10^\circ\text{C}−10∘C and 110∘C110^\circ\text{C}110∘C)

C

The freezing point of water (0∘C0^\circ\text{C}0∘C) and the temperature at which water is warmest and densest (4∘C4^\circ\text{C}4∘C)

D

The average room temperature (20∘C20^\circ\text{C}20∘C) and the normal human body temperature (37∘C37^\circ\text{C}37∘C)
