Which term describes the act of protecting something by surrounding it with material that reduces transmission of sound, heat, or electricity?

  1. a. Isolation

  2. b. Insulation

  3. c. Inertia

  4. d. Insulin

The correct answer is: b. Insulation

Insulation is the term that describes the act of surrounding something with material to reduce the transmission of sound, heat, or electricity. Isolation (A) refers to the act of separating something from others, and is typically used in social contexts. Inertia (C) is the property of matter that describes its resistance to change in motion. Insulin (D) is a hormone produced by the pancreas that regulates blood sugar levels. Thus, B is the only option that accurately describes the act of protecting something with material to reduce transmission of sound, heat, or electricity.
