# 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? - CBSE (Science) Class 11 - Physics

#### Question

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?
