Question

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

Explanation:

Thermal energy is related to the motion of particles. Electric energy involves electric - charge related phenomena. Potential energy is related to position or state. Internal energy is the total energy of all the particles in a substance, including kinetic and potential energy of the particles. Since Ryan is examining the energy of particles in a bar of gold, internal energy encompasses all forms of energy of those particles.

Answer:

internal energy
