Spontaneous process can be defined as things happening naturally without any external force concerning. Spontaneously process in physical chemistry is very important to know. In an opposite view, the process that is not concerned with naturally happening, but occurs by an external force is a non spontaneous process. The heat will flow higher temperature to lower temerature., it is a natural process. There need an external force to flow heat from lower temperature to higher temperature.Rolling of a ball from top of the hill to botom is a naturalprocess. But picking ball from botom to top is not natural.
