Final answer:
Spontaneous processes release free energy and move to a more stable state, following the second law of thermodynamics which states entropy always increases in a spontaneous process.
Explanation:
A spontaneous process is the time-evolution of a system in which it releases free energy and moves to a lower, more thermodynamically stable energy state. The second law of thermodynamics states that any spontaneous process increases the total entropy of a system or leaves it constant, never decreasing. Heat naturally transfers from higher to lower temperature bodies following this law.
