Nettetthermodynamics: [noun, plural in form but singular or plural in construction] physics that deals with the mechanical action or relations of heat. NettetIn thermodynamics, work is one of the three distinguished classes of thermodynamic process by which a thermodynamic system can interact with its surroundings in energy transfer. Thermodynamic work occurs … NettetThermodynamics is the study of the relationship between heat (or energy) and work. In other words, thermodynamics looks at how we can put energy into a system (whether it is a machine or a molecule) and make it do work.

"NettetThe work that the system does from B to C is counterbalanced by the work that is done to the system from D to A. Visualize the Carnot cycle illustrated on a PV diagram. We know that internal energy is a state variable, which means the internal energy at point A will always be the same regardless of the path that leads to point A. " - How thermodynamics work
