SUMMARY
The Kelvin scale is defined using the absolute zero as its null point and the triple point of water as a reference point. While absolute zero provides a fundamental basis, the triple point of water is necessary to establish a second reference for linearity. The degree Kelvin is equivalent in size to the degree Celsius, allowing for a consistent temperature measurement system. This dual-point definition enhances accuracy compared to relying solely on the Celsius scale's freezing and boiling points, which are influenced by pressure variations.
