State, Path, Process and Cycle

1 State: When all the properties of system have a definite value, then the system is in a definite state. Whenever there is change in anyone of the property, then the system is said to have a change of state.

2 Path: If all the change of states of system are plotted and all the points are conned, then the line joining the change of states of the system is called the path.

3 Process: When the path connecting the change of states of the system is specified, then this path is called Process. Example: constant pressure process, constant volume process etc.

4 Cycle:  When a system goes through different change of states and return backs to the original state, i.e., all the properties are identical to the original state, then the system is said have gone through a thermodynamic cycle.

How can the path of change of state be specified?

By identifying the thermodynamic variable at particular states

Thermodynamics path is the series of state passes during any thermodynamics process

is high grade energy(work) to low grade energy(heat) 100% efficient?
