Spontaneous Process Defined
Captions available
The idea
A spontaneous process is one that occurs on its own under a given set of conditions, without a continual outside input of energy.
In practice
Ice at room temperature melts on its own; no outside push is needed to start it.
Where people slip
Students often label any exothermic or "natural-seeming" process spontaneous without checking the actual conditions involved.
