Question

How did Kelvin find absolute zero?

Answer 1

To Kelvin's mind, absolute zero was where a temperature scale should begin, but for convenience, he used the markers and intervals of the widely-known Celsius scale as a base for his own. As such, in the Kelvin scale, water freezes at 273.15 K (0 C) and boils at 373.15 K, or 100 C.
