Detailed explanation-1: -Definition. The kelvin is defined by taking the fixed numerical value of the Boltzmann constant kB to be 1.380 649 × 10−23 when expressed in the unit J K−1, which is equal to kg m2s−2 K−1, where the kilogram, metre and second are defined in terms of , and ∆. This was a new definition in May 2019.
Detailed explanation-2: -The three most common units of measurement for temperature are Celsius, Fahrenheit, and kelvin. The Celsius scale is part of the metric system. The metric system of measurement also includes units of mass, such as kilograms, and units of length, such as kilometers.
Detailed explanation-3: -The kelvin (symbol: K) is the SI unit of temperature, and is one of the seven SI base units. It is defined as the fraction 1/273.16 of the thermodynamic (absolute) temperature of the triple point of water.
Detailed explanation-4: -The measurable properties of gases are mass, volume, pressure and temperature.
