But this is only valid for a closed system which is undergoing a cycle. For a process it can be written as −. Q 1 − 2 = U + W 1 − 2. Before we can start modelling these one should know how to model work and heat for different processes. So let us do that first. WebThermodynamic work occurs by a mechanism through which the system can spontaneously exert externally measured macroscopic forces on its surroundings. In the surroundings, such mechanical work can be made to lift a weight. The remaining two distinguished classes of thermodynamic process are heat and transfer of matter. csi frogger
