Question
Answer the following:
There were two fixed points in the original Celsius scale as mentioned above which were assigned the number 0 °C and 100 °C respectively. On the absolute scale, one of the fixed points is the triple-point of water, which on the Kelvin absolute scale is assigned the number 273.16 K. What is the other fixed point on this (Kelvin) scale?

Solution 1
The absolute zero or 0 K is the other fixed point on the Kelvin absolute scale.
Solution 2
On Kelvin’s absolute scale, there is only one fixed point, namely, the triple-point of water and there is no other fixed point.
