In my thermo class I'm currently taking, the professor constantly says thermal energy cannot be completely converted into energy of motion. Just to be clear, I'm not arguing this point. I'm just wondering why we say that, when earlier in the course it said that thermal energy at the macroscopic level is the kinetic energy of the particles at the microscopic level. It seems to me that heat transfer is just transfer of kinetic energy... so what am I missing?
