vaporization

The residual ortho-H2 molecules continue to isomerize to para-H2 during the storage, triggering partial vaporization of the liquid H2 and resulting in significant loss of H2 and energy.

His apocalypse prediction was delivered sans despair or even humor but, rather, in a casual “smoke ‘em if you got ‘em” tone of someone who’s way past the freaking out stage of accepting imminent vaporization.

This dovetailed with ASASSN-21qj’s long dimming, which, in a giant-impact scenario, would demand a dust cloud from the near-total vaporization of two similarly hefty worlds.

Many of these skeletons were contracted in a rigid “boxer position,” which is characteristic of rapid death by vaporization or dehydration.

Around 20 other belt-bound objects seen shedding mass — possibly because of comet-like periodic ice vaporization, wild spinning or recent impacts by asteroids — are considered candidates to be comets.
