Process Values Heat and Work
Over the previous chapters the internal state of a system has been described. A thermodynamic system can change its state and several possible changes of state have been discussed. For the further understanding it is essential to be familiar with the terms reversibility/irreversibility as well as with the idea of a quasi-static change of state. These approaches have been clarified in the previous Chaps. 7 and 8: By external impacts a system’s thermodynamic equilibrium can be disturbed and the system moves into a new balanced state.
