Kelvin scale
The Kelvin scale is a temperature scale used in physics and chemistry to measure absolute temperatures, developed by William Thomson (also known as Lord Kelvin). It is defined such that 0 K is absolute zero, the theoretical temperature at which all matter would have zero entropy, and the size of one degree is the same as the size of one degree on the Celsius scale. The Kelvin scale is used in scientific research, particularly in the fields of Thermodynamics and Superconductivity, as it provides a more intuitive and absolute way of measuring temperatures. The scale is also related to the concept of Absolute zero, which is the theoretical temperature at which all matter would have zero entropy.
