Eli5: How hot would water have to be for it to be vapor coming out of the tap?
In: Physics
Water can become vapor at virtually any temperature, even if it’s solid ice. But it sounds like you’re imagining a faucet spewing nothing but steam. I’m not sure how that would work exactly plumbing-wise, but I suspect the whole system (including any water fed into it) would have to be boiling (100 °C or 212 °F). Under normal circumstances (i.e outside of a pressurized vessel or something), you can’t really get water hotter than that.
