Second Law of Thermodynamics - Heat Energy, Entropy & Spontaneous Processes

This physics video tutorial provides a basic introduction into the second law of thermodynamics. It explains why heat flows from a hot object to a cold object. The second law of thermodynamics states that the change in entropy of a natural process is always a positive. For an ideal reversible process, the entropy change is equal to or greater than zero.
