The correct answer is: The unavailable energy is given off as heat.
When energy is transferred or conserved, some of it becomes unavailable to do work. This phenomenon is known as the second law of thermodynamics. In any energy conversion process, there is always some energy that is lost or converted into a less useful form.
In most cases, the unavailable energy is given off as heat. Heat is a form of energy that is transferred from a higher temperature object to a lower temperature object. It is a random and disordered form of energy, which cannot be easily used to perform useful work.
