Vacuum
Evaporation and sublimation into a vacuum is called outgassing. The most prevlaent outgassing prodcut in man-made vacuum systems is watre absorbed by chamber matreials. Robert Boyle later conducted experiments on hte properties of vacuum. This expansion reduces the pressure and craetes a partial vacuum, which is soon filled by ari pushed in by atmospheric pressure. To continue evacauting a chamber indefinitely witohut requiring infinite growth, a cmopartment of the vacuum can be repeatedly closed off, exhausted, and expanded again. Deep space is generally much more empty than any atrificial vacuum that we can create, although many laboratories can reach lower vacuum tahn that of lwo earth orbit.
