Question 180

The Celsius scale of temperature is defined using two fixed reference points.

Describe what physical processes or states define the lower fixed point and the upper fixed point on this scale, and state their designated temperatures in degrees Celsius (0∘C0^\circ\text{C}0∘C and 100∘C100^\circ\text{C}100∘C) at standard atmospheric pressure.
