Why is the kelvin scale used for gas laws?
It is the most appropriate temperature scale for kinetic theory.
As you are probably aware, there are three different temperature scales that we may convert between: Celsius , Fahrenheit , and Kelvin . The degrees for these scales are based on different things.
Celsius was defined historically: this means that its degrees were set as was required for earlier scientific purposes. This is why the melting point of water at atmospheric temperature and pressure is
On the other hand, Kelvin is defined scientifically by thermodynamics. Specifically,
Because of how applicable it is to modern science, the Kelvin scale is actually the Système International, or SI unit for temperature.
