What are the areas where thermodynamic is most important?

Thermodynamice is important in Air conditioning, pipeline working, automative work even in every part of mechanical funtioning Thermodynamics is important. Mechanical funtioning produces heat and here the role of thermodynamics start.

Thermodynamics is one of the most important branch and study in mechanical related subjects, as mechanics deals with the movement of parts, there exist force and friction and thus developing heat. The thermodynamics concept can extend from air conditioners and chillers to heater. Controlled environment to temperature reduction chamber. Pressure vessels to boilers and even automobiles. The most important concept looked forward is thermal insulation, heat retainment and some cases for heat transfer methods
