Which one of the following correctly defines 1 K, as per the internati...
Explanation:
The correct definition of 1 K, as per the internationally accepted definition of temperature scale, is option 'D': 1/273.15th of the triple point of water. Let's break down the explanation to understand why.
Triple Point of Water:
The triple point of water is a unique combination of temperature and pressure at which the three phases of water, namely solid (ice), liquid, and gas (water vapor), can coexist in equilibrium. At this point, the temperature and pressure are precisely defined. The triple point of water is a fundamental reference point for temperature measurements.
Definition of Kelvin (K):
The Kelvin scale is an absolute temperature scale, with 0 K representing absolute zero, the lowest possible temperature. The Kelvin scale is widely used in scientific and engineering applications, where precise temperature measurements are required.
Relation between Kelvin and Celsius:
The Kelvin scale is related to the Celsius scale (also known as Centigrade scale) by the following equation:
Kelvin = Celsius + 273.15
1 K as per the Internationally Accepted Definition:
According to the internationally accepted definition, 1 K is defined as 1/273.15th of the triple point of water. This means that the temperature difference between the triple point of water and absolute zero (0 K) is divided into 273.15 equal intervals, with each interval being 1 K.
Significance of the Definition:
This definition ensures that the Kelvin scale is based on a physically meaningful reference point, the triple point of water. It provides a consistent and reproducible temperature scale that can be universally understood and applied. It also allows for precise temperature measurements and comparisons in scientific experiments and engineering calculations.
Other Options:
Let's briefly consider the other options mentioned in the question and see why they are incorrect:
a) 1/100th of the difference between the normal boiling point and normal freezing point of water: This option does not correspond to the internationally accepted definition of 1 K.
b) 1/273.15th of the normal freezing point of water: This option does not consider the unique reference point of the triple point of water.
c) 100 times the difference between the triple point of water and the normal freezing point of water: This option does not divide the temperature difference into equal intervals and does not align with the Kelvin scale definition.
In conclusion, the internationally accepted definition of 1 K is 1/273.15th of the triple point of water. This definition ensures the Kelvin scale's accuracy, reproducibility, and consistency in temperature measurements.
