Consider a material that is being heated for a certain period of time. During that time, energy is transferred into the system and both the average KE of the particles and the potential energy of the system of particles increase. Which of the following processes could this describe? A. Heating the material while it remains in its solid state. B. Heating the material during the melting process. C. Heating the material while it remains in its liquid state. D. Heating the material during either the melting process or the boiling process. E. Heating the material while it remains in either its solid or liquid state (choices A and C)
