[–] village604@adultswim.fan 48 points 6 months ago* (last edited 6 months ago) (3 children) It's actually not a bad question, just one people don't really think about. Why does room temperature water sublimate evaporate? It's because the temperature is an average, and some molecules at the surface have enough energy to break their polar bonds. permalink fedilink source parent hideshow 6 child comments replies: [–] wolfpack86@lemmy.world 27 points 6 months ago (4 children) Water doesn't sublimate. Sublimation is solid to gaseous phase change. permalink fedilink source parent hideshow 8 child comments replies: [–] village604@adultswim.fan 5 points 6 months ago Fixed permalink fedilink source parent [–] anothercatgirl@lemmy.blahaj.zone 3 points 6 months ago sublimation is poorly defined in our context. permalink fedilink source parent [–] Tinidril@midwest.social 2 points 6 months ago (1 child) Technically, water does sublimate, just not at normal earth pressures. Below 0.6 kPa it transitions straight from solid to gas. permalink fedilink source parent hideshow 2 child comments replies: [–] wolfpack86@lemmy.world 1 point 5 months ago (1 child) Theres a word for solid forms of water...

Substitute teachers aren't playing the good stuff anymore permalink fedilink source parent [–] Hideakikarate@sh.itjust.works 22 points 6 months ago (1 child) I wanna say Bill Nye had a little contraption that explained this phenomenon. A cup with a piston on one end that vibrated. The top part of the cup had a ring in the center where little balls in the cup could fit. The piston represented the temperature (energy). Even at a lower temperature, some balls could randomly fly into the little hole and into the other partition. Turning the temperature up (increasing the speed and power of the piston) made more balls more frequently "evaporate." I wish I could find that demonstration again. permalink fedilink source parent hideshow 2 child comments replies: [–] GraniteM@lemmy.world 3 points 6 months ago Maybe you just gotta piston pound your balls for yourself, comrade. permalink fedilink source parent
