Abstract
Some phenomena, though representing instances of entropy change, appear to defy the description of entropy as a function of energy spreading and sharing. Despite its great utility such a description is sometimes difficult to apply because a function levelling down available energy not always exactly acts as a spreading and sharing function. The concept of a physical function levelling down available energy is therefore preferable to understand entropy and the second law of thermodynamics because it has a more general value.
