Each artefacts are as opposed in vacuum and in air. By evaluating The 2 artefacts of similar nominal fat, the large volume change reflects the air buoyancy and thus results in a remarkably precise determination of air density. The buoyancy artefacts are mostly employed for the M_one vacuum mass comparator. https://donovanmetix.jiliblog.com/88065852/examine-this-report-on-bailing-wire
