Answer:
Petrol taken in an open vessel disappears after some time because of the phenomenon called Sublimation.
Explanation:
Sublimation is the process in which the matter converts directly into gaseous state from solid and vice versa. It is caused by the absorption of heat which provides enough energy for some molecules to overcome the attractive forces of their neighbours and escape into the vapour phase. It is an endothermic change.
