Ryan is examining the energy of the particles in a bar of gold. What is Ryan most likely studying?

thermal energy
electric energy
potential energy
internal energy

1 answer

Ryan is most likely studying internal energy. Internal energy refers to the total energy contained within a system, which includes the kinetic and potential energies of the particles (atoms and molecules) that make up the material, such as a bar of gold. Since he is examining the energy of the particles specifically, internal energy is the most relevant concept.
