Isothermal Process : A process is said to be isothermal in case the temperature of the system remains fixed or constant. Ex : Operation is carried out at constant temperature.
Adiabatic Process : In adiabatic process, no exchange of heat between the system and surrounding is possible. Ex : The system is completely isolated or insolated from the surrounding.
Isobaric Process : A process is said to be isobaric in which the pressure remains constant throughout the process. dp =0
Isochoric Process : A process carried out at constant volume is called isochoric process. Thus, for isochoric process , dV =0
Cyclic Process : When a system undergoes a series of changes and finally returns initial state, it is called cyclic process. There is no change in energy in cyclic process, d E = 0
Reversible Process : A process is said to be reversible in case it is carried out infinitesimally slowly so that all change occurring in the direct process can be exactly reversed and the system and surroundings remain in state of equilibrium at any stage in the process.
Irreversible process : It is a process in which the change is brought rapidly and system does not have chance to achieve equilibrium. Here the force that makes the product is greater than the force which is to carry in the reverse process.
