comment Why the energy of a marshmallow is so huge?
While they are closely related, I don't know that I would say rest energy and internal energy are synonyms. I feel that I have answered the question, but I know of no way to explain the concept other than how I already have. Perhaps someone with a different viewpoint can come in and clarify.

comment What are the fields in this problem?
Not sure this question type is appropriate for Stack Exchange, it may be closed. But it doesn't seem like the Author's question has anything to do electric fields. Best of luck.

comment Why the energy of a marshmallow is so huge?
Yes, the "internal energy" is the sum of the rest energies that make up the system. That is what I am saying because it is really that straightforward. I am not sure what you mean when you say "macro to micro scale." Internal energy is an inherently micro-scale phenomenon. As RedGrittyBrick brings up, there are other types of energy that can be contained in the system, but internal energy is strictly determined by particle level interactions.

comment What is a bulk phase transition?
I have the same confusion as you on that. I did stumble across one paper that mentioned a comparison of Surface Phase transition vs. Bulk Phase transition. That would seem to indicate that there is at least some meaningful difference. If I were to take a guess, I would think bulk phase transition would be when the entire material undergoes a phase transition (i.e. sublimation) vs surface phase transition where just the surface of the material is undergoing a phase transition (i.e. water freezing on a lake)

comment What is a bulk phase transition?
I'm not an expert so I won't submit it as a definitive answer but when it comes to complex physical terms I find it helpful to break them down into their constituent parts. A phase transition occurs when a material changes phase (liquid -> gas, gas -> solid, etc.). When talking about materials the term "Bulk" generally refers to a volume. So putting the terms together, it would seem that a "bulk phase transition" would be when an entire material changes phase at once.

comment Calculating work done on an ideal gas
In this usage $p(V)$ is simply referring to a function relating pressure to Volume. You will want to use the ideal gas law.
