Question

the degradation of energy ________. occurs as the incoherent motion of particles transforms into coherent motion. is irreversible is reversible occurs when low - quality energy is transformed to high - quality energy

Explanation:

Energy degradation refers to the process where energy becomes less useful. According to the second law of thermodynamics, energy tends to disperse and become less organized. Incoherent motion (like random molecular motion in heat) is less useful than coherent motion (like mechanical motion). Also, once energy degrades (e.g., high - quality energy like fuel's chemical energy degrades to low - quality heat energy), it cannot spontaneously reverse.

Answer:

is irreversible
