← ScienceWhich 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.
