CIP4 Science Progression Practice Test

Sound energy is the correct answer because it is the form of energy that travels in waves and can be detected by our ears. This type of energy is produced when an object vibrates, creating compressions and rarefactions in the air or another medium, which our auditory system interprets as sound.

When sound waves travel through the air, they cause pressure changes that can be picked up by the organs in our ears, allowing us to perceive different sounds. Sound energy is essential for communication, music, and many everyday activities in our lives.

Other forms of energy, such as thermal, electrical, and nuclear energy, exist in different contexts and do not travel in the form of sound waves that can be directly perceived by our auditory system. Thermal energy relates to heat transfer, electrical energy pertains to the flow of electric charge, and nuclear energy involves the energy released during nuclear reactions. None of these directly correspond to what we can hear.
