Other forms: evaporated, evaporates, evaporating
To evaporate is to turn to vapour and disappear. The water evaporated, evaporate in the heat, support evaporated.
It happens at any temperature, not only at boiling, which is why a puddle dries on a cold day. The figurative use is common and exact: support that evaporates goes without anybody deciding to withdraw it.
