When a television is turned on, it transforms electrical energy into light and sound energy. However, a significant portion of the electrical energy is also converted into heat, which dissipates into the surroundings. This energy spreading into less useful forms, like heat, is related to what fundamental principle?
✓ Correct Answer: Option B
The second law of thermodynamics states that in a closed system, entropy (disorder) tends to increase. This means energy transformations are never 100% efficient, and some energy is always converted into less useful forms, often heat, increasing the system's disorder.
