Processes and Cycles

1.8.1 Process

The process takes place when here is a change of system in the state. The progression of states that occurs through some changes of states is called path. The paths are entirely identified in the process.

1.8.2 Mechanical Equilibrium

The total number of processes in proper sequence all in a thermodynamic equilibrium where the last stage is same as the initial one then it is called mechanical equilibrium.

In the above given Fig. 1.6 it represents a process A – B and 1-2-1 as a cycle. Many methods together form a complete cycle. Now after going through some processes, the system finally regains its original state. 1-2-1 is a cyclic process.
