Topics to be covered Laws of thermodynamics Zeroth law First law Second law and Third law Thermal Processes Isobaric Isochoric adiabatic and Isothermal Heat engines Refrigerators Airconditioners and Heat pumps . No engine, working in a continuous cycle, can take heat from a reservoir at a single temperature and convert that heat completely to work.. Therefore, no engine can have a greater efficiency than a Carnot engine operating between the same two temperatures..
