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?

A Conservation of mass
B The second law of thermodynamics (entropy)
C Newton's Third Law of Motion
D The law of definite proportions

✓ 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.

💡 Why is B) the correct answer?

The correct answer to the question "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?" is Option B: The second law of thermodynamics (entropy).

The other options — A) Conservation of mass, C) Newton's Third Law of Motion, D) The law of definite proportions — are incorrect for this GED Exam Prep question. As explained above: 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 …
