In thermodynamics, a process is the path of the succession of states through which a system passes. A process can also be called a change in state.
There are numerous different types of processes including but not limited to the following:
• Adiabatic process
• Ideal process
• Irreversible process
• Isentropic process
• Isobaric process
• Isochoric process
• Isothermal process
• Nonequilibrium process
• Polytropic process
• Quasi-equilibrium process
• Reversible process
• Steady-state process
• Steady-flow process
Note: above are all thermodynamic processes.
