Types of thermodynamic processes

We say that a thermodynamic process has occurred when the system changes from one state (initial) to another state (final).

  • Constant Volume (Isochoric) process:  It is a process during which the volume of the system is kept constant.
  • Isobaric process:  It is a process during which the pressure of the system is kept constant.
  • Isothermal process:  When the temperature of a system remains constant during a process, we call it isothermal. Heat may flow in or out of the system during an isothermal process.
  • Adiabatic process:  No heat can flow from the system to the surroundings or vice versa.
