An Isobaric process is a thermodynamic process in which the pressure stays constant: ΔP = 0. This will happens when the working substance remains in a perfect thermal contact with the surroundings. Adiabatic Process A process, in which the working substance neither receives nor gives out heat to its surrounding, during its expansion or compression is called an adiabatic process. P> Patm. Why is quasi-equilibrium important? Easy to calculate. International units system. Thanks!

An isobaric process is a thermodynamic process in which the pressure stays constant.
An adiabatic process is a process in which the working substance neither receives nor gives out heat to its surrounding, during its expansion or compression.
Quasi-equilibrium serves as a standard to compare actual processes.
The international units system is used to make calculations easier.
