Final answer:
In the process of conduction, what moves are the particles (atoms and molecules), which vibrate and transfer energy through collisions. This is different from convection, which involves fluid movement, and radiation, which involves electromagnetic waves.
Step-by-step explanation:
The process of conduction involves the movement and transfer of heat by the direct contact and collision of particles. In conduction, these particles are typically atoms and molecules that vibrate and transfer energy to neighboring particles without the movement of the material as a whole. This contrasts with convection, which involves the bulk movement of a fluid (gas or liquid) and helps distribute heat through that movement, and radiation, which involves the transfer of heat through electromagnetic waves.
When considering the options provided for what is moving in the process of conduction - (A) Air, (B) Particles, (C) Electromagnetic Waves, and (D) Heat - the correct answer would be (B) Particles. This is because, during conduction, it is the energetic motion and collisions of particles that are primarily responsible for the transfer of heat energy from one area to another.
