The correct answer is: The unavailable energy is given off as heat.
The unavailable energy is given off as heat.
The correct answer is: The unavailable energy is given off as heat.
When energy is transferred or conserved, some of it inevitably becomes unavailable to do useful work. This is known as the "law of energy conservation" or the "second law of thermodynamics." According to this law, as energy is converted from one form to another, some of it is always dissipated as heat.
Heat energy is a form of energy that is difficult to convert back into useful work. It is usually dispersed into the environment, leading to an increase in the overall entropy, or disorder, of the system.
So, when energy becomes unavailable, it is usually given off as heat and cannot be used to perform useful work, such as powering machines or performing tasks.
