What is the main difference between elastic energy and sound energy?

Elastic energy exists in the distortion of a material, while sound energy exists in pressure waves through a fluid. (correct)

Elastic energy can be stored in potential form, but sound energy cannot.

Elastic energy is potential energy, while sound energy is kinetic energy.

Elastic energy is found in a mechanical wave, while sound energy is produced by the vibrations and motions of particles.

How is heat defined in terms of kinetic energy?

Heat is measured as temperature, representing the average kinetic energy of particles. (correct)

Heat is the potential energy stored in vibrations of particles.

Heat is the energy transferred by systems into macroscopic surroundings.

Heat is interchangeable with work due to its potential to transform into motion.

Which process exemplifies the interchangeability of work and heat by converting mechanical motion into heat?

The rising of particles of air above cooler or denser air.

The propagation of waves through an elastic material.

The transformation of friction from rubbing sticks together into kinetic energy. (correct)

The convection process in hot air balloons.
