Now back onto mercury As any other material in liquid state it of course vaporizes even when far from boiling point. The warmer the faster though.

True, but as far as I know only when at given temperature and pressure there is direct transition from solid state to gas state.

Many do it at room temp in open air.

Indeed - because for those these are the right conditions. For example is you put frozen C02 in room conditions it does not melt first and than evaporate - it sublimates, because liquid state of C02 only exists at pressures 5 times the normal pressure (at give temperature range only of course).
