"Couplefew" does not seem to be an actual word.

Some liquids with very low vapor pressures have enough surface tension to prevent bubbles from forming, and will only slowly evaporate from their surface, similar to solids (which also have non-zero vapor pressures). Silicone oils and polyphenyl ethers are routinely used in ultra-high vacuum applications, even in the pumps used to achieve such vacuums: en.wikipedia.org/wiki/Diffusion_pump | |
| May 17, 2022 at 22:20 | comment | added | No Nonsense | @user253751 All liquids will boil in vacuum. Liquids boil once the ambient pressure is equal to or drops below liquid's vapour pressure, and in vacuum the ambient pressure is zero; meanwhile, all liquids have a non-zero vapor pressure. | |

Removed liquid air entry: was based on a misunderstanding
