I.e. the volumes of gases under the ideal gas law scaled linearly with degrees celcius by about 1/273rd between 0-100C - which led to the prediction that the lowest possible temperature a gas could be was -273C (because that would be the point where it theoretically would have absolutely zero volume).

No horse in this race, but this is cool as fuck. So that’s how the first tries at measuring absolute zero were made.
