Of course water evaporates at ambient temperature.
But in the “dish of water on the table” scenario you propose, the latent heat of vaporization cooling the water as it evaporates is a gradual loss, replenished by the ambient air.
Ever get cold getting out of a swimming pool or a shower? That’s latent heat of vaporization.
If you heat water, it evaporates faster. The higher the temperature you heat it to, the faster it evaporates.
You don’t have to heat it to boiling to get it to vaporize.
That was the point I made that you went full retard on.
