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 entropy. According to the second law of thermodynamics, in any energy conversion or transfer, some energy will always be lost to the surroundings as heat. This means that the unavailable energy is given off as heat, which increases the overall disorder or randomness of the system. Heat energy is a form of energy that cannot be used to do work directly, but it can still have an impact on the temperature of the surroundings.
