All three boxes are made from the same material. Explain at the molecular/atomic level how heat is transferred from box A to Box C. Estimate the final temperature of Boxes A,B and C. What law is this process describin? State the Law.

We can safely say that all boxes will eventfully reach an ambient temperature what ever it may be. The temperature of each box is a time dependent quantity. So the question is when you want to know the temperature of each box and at what point?
There are three aspects of heat must be considered:
1. Conduction
2. Radiation
3. Convection.
The information missing: are boxes touching, how, what geometry, what is medium surrounding these boxes (gas, liquid), and so on.
Finally Is the system adiabatic processes (thermally insulated)?

well part of this question can be answered. at a molecular level "heat" is directly proportional to the average kinetic energy of the molecules in the substance. assuming that the two substances are in contact, the higher energy molecules in the higher temperature box will interact with and give energy to the molecules in the second and so on. this process will continue until all of the boxes are at the same temperature. the law which describes this is the second law of thermodynamics if i remember correctly.

Thermal Radiation is what you're talking about here. You have emmissivity and absobtion going on. But I can't tell you the the final temperature without knowing how long the boxes are next to eachother. That is an important element to know.
1 = S (emmitted) + S (absorbed)
But I also need a time component ....
Size of boxes... Is Box A bigger than Box C
etc...
This question cannot be accurately answered...

Theoretically, the end result would be 3 boxes at 33 C

All three will eventually end up at room temperature unless energy is put into the system.

Can't say till you tell us about box B, unles we guess.
