Ice melting
A spontaneous process is capable of proceeding in a given direction, as written or described, without needing to be driven by an outside source of energy. The term is used to refer to macro processes in which entropy increases; such as a smell diffusing in a room, ice melting in lukewarm water, salt dissolving in water, and iron rusting. Is it always spontaneous that an ice melts into liquid water?

we all know that ice can further cooled and then it becomes harder! we just have to think when shall it happen ............. it shall only happen when the temperature of the immediate surrounding is lower than the temperature of the ice mass!
