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.

Water doesn't sublimate. Sublimation is solid to gaseous phase change.

Technically, water does sublimate, just not at normal earth pressures. Below 0.6 kPa it transitions straight from solid to gas.

Theres a word for solid forms of water... It's called ice.

[-] Tinidril@midwest.social 1 points 2 months ago

You referred to it as "solid" first, so I have no idea where you think I was confused on this point.

[-] anothercatgirl 3 points 3 months ago

sublimation is poorly defined in our context.

Pretty sure Bill Nye taught me this. Substitute teachers aren't playing the good stuff anymore

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.

Maybe you just gotta piston pound your balls for yourself, comrade.
