#### 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.

Is there an error in this question or solution?

Solution 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? Concept: Temperature and Heat.
