Witryna7 kwi 2024 · 6.3A: Overview of Sublimation. Some compounds are capable of sublimation, which is the direct phase change from solid to gas. Solid carbon dioxide is an example of a substance that sublimes readily at atmospheric pressure, as a chunk of dry ice will not melt, but will seem to "disappear" as it turns directly into carbon dioxide … Witrynathermal decomposition. Refractory organics may survive for hours or days in a lab, but not weeks to centuries in a nebular disk. Considering that the refractory organics sublimate in 100 years at 478-508 K (Table S2), we adopt 500 K as the effective sublimation temperature of refractory carbon carriers in the solar nebula.
