I was wondering - when pressure is applied to solids, do they heat up? Not pressure like an impact - I'm not talking about conversion of kinetic energy. But suppose a piece of iron is put in a hydraulic press and the pressure increases slowly. More specifically, I'm wondering about the rocks deep inside the earth. Do solids generate heat simply by being under pressure? It seems like high pressure could restrict the thermal motions of the molecules, causing them to generate heat simply by their vibrations. But since solids are generally incompressible, I didn't know if this would happen. I'm posting this here because I thought the answer may be more related to Q/M than to classical physics.
