The rate at which something evaporates is determined by their atoms bond strength, weight has less importance. The reason petrol evaporates fast (and melts and boils at low temperatures) is because they only have London forces, which is the weakest weak bond.

Your request for a duel is held in a queue and will be answered as soon as I’ve dealt with my colleague who inconsiderately has the same initials as me.
