Which consequence results when high vacuum lowers boiling points?

A)Reduced sensor accuracy at cryogenic temperatures
B)Polymer outgassing contaminates molecular beam epitaxy
C)Enhanced heat conduction of noble gasses
D)Improved refractive index matching of liquids

💡 Explanation

Polymer outgassing increases under vacuum owing to vapor pressure elevation because of the Clausius-Clapeyron relation. Polymer contaminants sublime through enhanced vaporization, therefore the molecular sample is compromised, rather than the alternative of only affecting sensor behaviour or optical properties.
