There is kind of thermodinamic meaning in several mechanical engineering books!
based on wikipedia we try to share it's meaning. In physics, thermodynamics (from the Greek therme, meaning "heat" and dynamis, meaning "power") is the study of the conversion of energy into work and heat and its relation to macroscopic variables such as temperature and pressure. Its underpinnings, based upon statistical predictions of the collective motion of particles from their microscopic behavior, is the field of statistical thermodynamics, a branch of statistical mechanics. Historically, thermodynamics developed out of need to increase the efficiency of early steam engines.
